Ongoing Projects

AHEAD - ‘Advanced Techniques for Quantification and Modelling of Phase-Change Processes of Renewable Fuels and their Blends’

Call: H2020-MSCA-IF-2017
Fellow: Dr I. Karathanassis, PI: Prof M. Gavaises, Co-I: Dr Lyle Pickett, Sandia National Labs, US
Budget: €252,000

Current international policies dictate the gradual disengagement of industry from fossil fuels within the next three decades. In order such a transition to become a reality, novel fuel delivery and combustion concepts capable of efficiently utilising biomass-derived fuels must be designed and developed. The main objective of ‘AHEAD’ is the simultaneous experimental characterisation of the phase-change processes within fuel injectors (cavitation and flash boiling) and at the nozzle exit (evaporation and trans/supercritical phase-change) under realistic injector configurations and air thermodynamic conditions for liquid biofuels, as well as their blends with fossil fuels. The obtained measurements will guide the formulation of novel numerical models quantifying the relevant mass/heat transfer processes. The project innovative nature spans across diverse research aspects with emphasis on renewable alternatives for Diesel and gasoline; it is expected to assist major energy and automotive industries to meet the goals imposed regarding the utilisation of renewable fuels.

EDEM - Experimentally Validated DNS and LES Approaches for Fuel Injection, Mixing and Combustion of Dual-Fuel Engines

Call: H2020-MSCA-EID-2018
PI: Prof M. Gavaises, Co-I: Dr I. Karathanassis
Budget: ⁓ €4,150,000 in total - €1,170,000 awarded to City

Economical, geopolitical and social trends, apart from the well-posed environmental concerns, have precipitated legislative actions for the partial substitution of Diesel by cleaner fuels and have boosted industrial interest on the development of IC engines capable of handling both liquid/gaseous fuel mixtures. The combustion process in these, so-called, dual-fuel engines comprises the compression ignition of Diesel fuel injected in a homogenized gaseous (or liquid) fuel/air mixture. At dual-fuel combustion, most Diesel fuel is burned in premixed combustion and, thus, soot formation is less. Furthermore, depending on the carbon content of the primary fuel, dual fuel operation mode can lead to significant decrease in CO2 emissions. The aim of ‘EDEM’ is to develop and validate DNS/LES methodologies for fuel injection, mixing and combustion processes relevant to conditions and fuels combustion strategies realised in dual-fuel engines. Furthermore, to apply the newly derived models to the design of more efficient engines and to estimate the environmental impact of the proposed concept.

I-BAT - Immersed-cooling Concepts for Electric Vehicle Battery Packs using Viscoelastic Heat Transfer Liquids

Call: H2020-FETOPEN-2018-2019-2020-01
PI: Dr I. Karathanassis, Co-I: Prof M. Gavaises
Budget: ⁓ €2,950,000 in total - €838,000 awarded to City

The penetration of plug-in EVs in the world market faces considerable technological challenges. The performance of battery electric drives is influenced, among others, by the power density and efficiency of the EV Battery Thermal System (BTMS). Lithium-ion batteries require a temperature of 15-60 °C for optimal operation, with high demands on temperature uniformity between the cells. The power density of the battery cooling systems has to be doubled compared to current state-of-the-art to enable powerful and compact drives. This challenge is met by innovative coolants, which have shown considerable potential for increasing the cooling effect and reducing pump losses in basic investigations. The subject of work is the synthesis and characterisation of oil-based coolants with optimal rheological and thermal properties suitable for EV BTMSs. The novel fluids to improve heat transfer consist of a viscoelastic liquid carrier matrix with suspended nanoparticles.  The newly developed nano-coolants will be tested in a BTMS prototype to prove that these improvements have the potential to revolutionise the relevant transport sector.

Next generation waste-heat recovery systems based on two-phase expansion (RAEng Research Fellowship)

PI: Dr Martin White
Funder: RAEng
Project title: Next generation waste-heat recovery systems based on two-phase expansion
Start: Sep 2020
End: Aug 2024

The generation of power from waste heat using organic Rankine cycles (ORC) could be enhanced by up to 30% through two-phase expansion. However, this has not been successfully realised due to a lack of two-phase expanders. Dr White’s RAEng Research Fellowship seeks to explore the design of two-phase turbomachinery for this application through a combination of numerical and experimental investigations of two-phase expansion processes, and system optimisation of thermodynamic systems involving two-phase expansion. The ultimate aim of this research is to develop fundamental understanding, alongside advanced modelling and simulated methods, of the two-phase expansion of unconventional working fluids, and to investigate the concept at a laboratory scale.

SCOTWOHR

PI: Prof Naser Sayma
Co-I: Prof Manolis Gavaises, Dr Mathew Read, Dr Martin White
Funder: EPSRC
Project title: SCOTWOHR – Industrial waste heat recovery using supercritical carbon dioxide cycles
Start: Jan 2021
End: Dec 2023

Increased pressure on reducing the carbon footprint from energy intensive industry with substantial waste heat streams is leading to the need to develop efficient and cost-effective waste heat recovery technologies. Supercritical carbon dioxide (sCO2) systems have significant potential for these applications, but there remain significant technical challenges that need to be overcome in relation to the key system components. The focus of this project is to improve the fundamental understanding of the performance sCO2 cycles and the design aspects of the key components, through targeting the following objectives:

  • to identify the optimal cycle configuration for sCO2 power systems with power outputs of a few hundred kilowatts for WHR applications (~ 400-800 °C) based on multi-objective techno-economic optimisation accounting for design and off-design operation with variable or intermittent heat stream;
  • to explore design innovations for small-scale sCO2 turbomachines that can extend beyond current state-of-the-art operating conditions, and improve fundamental understanding of condensation, non- ideal gas effects, and stability of sCO2 compressors operating near the critical point;
  • to investigate innovative heat exchanger designs, materials and fabrication methods for different cycle configurations and develop heat exchangers for direct high temperature (up to 800 °C) waste heat to supercritical fluid heat recovery;
  • to characterise the transient operation of small-scale sCO2 power systems operating at design and off-design conditions with variable or intermittent heat streams and identify suitable real-time control strategies to maximise system performance across a wide range of operating conditions.

SCARABEUS

PI: Prof Naser Sayma
Co-I: Dr Martin White
Funder: H2020
Project title: SCARABEUS -Supercritical carbon dioxide/alternative fluid blends for efficiency upgrade of solar power plant
Start: Apr 2019
End: Mar 2023
Website here

City is leading the turbomachinery work package of the SCARABEUS project. The project aims to demonstrate that the application of supercritical CO2 blends to concentrated-solar power plants has the potential to reduce CAPEX by 30% and OPEX by 35% with respect to state-of-the-art steam cycles, thus exceeding the reduction achievable with standard supercritical CO2 technology. This translated into a levelized cost of electricity lower than 96 €/MWh, which is 30% lower than currently possible.

As the leader of work package 3, the team at City is focussing on the design of the turbomachinery components for the SCARABEUS project. The objectives are:

  • to develop innovative turbomachinery designs that can operate with high efficiency across the range of anticipated variable operating conditions;
  • to provide data to enable accurate calculations of cycle performance and costing of the proposed plant;
  • to identify a suitable pump for the system.

UNIFIED - Fuel injection from subcritical to supercritical P-T conditions: a unified methodology for coupled in-nozzle flow, atomisation and air-fuel mixing processes

Call: H2020-MSCA-IF-2016
Fellow: Dr Foivos Koukouvinis, PI: Prof M. Gavaises, Co-I: Dr Lyle Pickett, Sandia National Labs, US
Budget: €344,000

Fossil fuel consumption is expected to almost double over the next 3 decades in order to meet the increasing demand for infrastructure, trade and transportation. Development of engines complying with the forthcoming 2020 emission legislations, relies on the effective design of advanced high pressure fuel injection systems and represents a key industrial priority. Emissions can be reduced when fuel is injected against air at P-T conditions well above the fuel’s critical point; the prevailing supercritical fluid conditions result to disappearance of the liquid-gas interface, which in turn, reduces vaporisation time and enhances significantly air-fuel mixing. Combination of experiments (outgoing phase) with CFD simulations (return phase) of the in-nozzle flow, fuel atomisation and mixing processes under such conditions form the core subject of the proposed research. The experimental work includes currently unknown physical properties  measurements near the fuel’s critical point; these will be modelled with complex equations of state for a wide range of P-T conditions. Moreover, the state-of-the-art experimental techniques and equipment of the US host, will be employed for quantifying the near-nozzle fuel atomisation and mixing at those conditions. These experimental data will guide the development and validation of a new state-of-the-art CFD model able to couple the aforementioned multi-phase flow  processes through a combination of physical models and numerical methods. These include interface capturing of immiscible and diffused interfaces, scale-resolved turbulence, mass transfer rate (cavitation and vaporisation) and real-fluid thermodynamics addressing the compressibility effects for the liquid-vapour-air mixture. The project brings together research, academic and industrial experts from the US and Europe. It will advance scientific knowledge and will facilitate the design of less polluting engines for the benefit of the European area and society as a whole

UCOM – Ultrasound Cavitation in Soft Materials

Call: H2020-MSCA-ITN-2018
PI: Prof M. Gavaises, Co-I: Dr F.Koukouvinis
Budget: €4,211,733 (€1,1170,000 awarded to City)

The pressures and temperatures developing during the interactions of shockwaves with cavitation bubbles and soft matter induce complex phenomena, both at physical and biochemical levels. These have a non- exhaustive range of relevant applications including ultrasound-based therapies, surface cleaning and food processing. Our aim is to explore these processes both in micro and macroscales using experiments and to develop new computational capabilities for their simulations. Measurements will include temperature/ species forming in collapsing bubbles, identifying chemical reactions and possible tissue interaction, such as protein denaturation and agglomeration; tissue cavitation threshold and its control using nanoparticles, allowing development of new cavitation-mimicking-tissue materials extrapolating to actual tissue properties that will be used for in-vitro testing of equipment with minimum collateral damages. Computations will be based on advanced multi-resolution methods coupling fluid flow, chemical reactions and deforming material mechanics solvers, with physically consistent thermodynamic closure models for the involved materials; pressure wave propagation, bubble nucleation and material damage effects will link microscale phenomena to macroscale. Uncertainty quantification techniques will link computations with experimental data. UCOM builds upon the strong foundations of the PIs and their teams in training researchers in computational and experimental methods on cavitation and their strong record to successfully integrate research and technical applications. The final goal of the research and training program is to explore the enormous potential of the new and experimentally validated computational tools to guide breakthrough innovations and high-impact, high-tech technologies ranging across different sectors that all eventually enhance their careers and will be serving the well-being.
