Thermo-Fluids Research Centre

An internationally leading centre in fundamental and applied research in the field of fluid flow with heat and mass transfer and fluid-structure interactions.

The activities of the Centre are split in three research groups: Multi-phase flows, Centre for Compressor Technology and the Turbomachinery and Energy Systems Research Group. Computational, analytical and applied research is supported by state-of-the-art experimental facilities and in-house developed numerical tools.

About the Centre

The Centre has access to facilities and test cells devoted to instrumentation and testing from micro-scales, to compressors, turbines, IC engines and large marine propellers, utilising advanced optical, laser and X-ray diagnostic techniques. Expertise exists in computational mechanics, through the development of in-house CFD codes for turbulent compressible and incompressible flows utilising real-fluid thermodynamics. Heat and mass transfer, phase-change, fluid-structure interactions and complex chemical processes are addressed. Understanding the intrinsic physical phenomena from nano- to macro-scales and their wide range of applications, can lead to the design of engineering systems and pave the way towards new technologies

The Centre has a vast network of national and international collaborations over a wide range of engineering sectors; it receives funding from the European Union, EPSRC, InnovateUK and industries. We are committed to research towards reduction of emission from combustion engines, better utilisation of fuels, improvement of the efficiency of a vast range of fluid machinery, design of new engineering concepts for energy utilisation and bio-engineering applications aiming towards the well-being.

Research Area

Multi-phase flows

Multi-phase flows with interfacial transport phenomena play a dominant role in a non-exhaustive list of applications, including liquid injection into all types of combustion engines, fuel processing, fluid machinery, transformative energy technologies, heat pipes and cooling systems, air-conditioning and refrigeration, industrial processes as well as ultrasound and micro-fluidics directly relevant to biology and medicine. We perform fundamental research in the area multi-phase flows across scales (nano/meso to macro), develop relevant state-of-the-art computational models and apply advanced experimental techniques for their validation. Phase-change processes such as cavitation, flash boiling, vaporisation and trans/supercritical phase-change are explored in applications of significant technological, environmental, biomedical and economic importance at global scale.

Centre for Compressor Technology

Expertise of the Centre for Compressor Technology in rotor profiling for screw machines, utilisation of low temperature heat sources by using screw expanders and Computational fluid dynamics (CFD) in screw machines resulted in development of in-house codes which are now widely used in industry. Investigation of multiphase and leakage flows in screw machines, the use of composite materials and additive manufacturing techniques and research in profiling for novel screw machines are alongside design of screw machines for industry the main activities of the Centre. The Centre also hosts the Materials Group specialising in semi-solid and laser processing of materials. The fundamental and applied research conducted in the Centre since it was established in 1995 resulted in 12 patents been granted, three monographs, 85 journal papers, 166 conference publications and over 200 industrial reports, for which the members of the Centre received 13 professional awards and prizes.

The Turbomachinery and Energy Systems Research Group

The Turbomachinery and Energy Systems Research Group has been conducting fundamental and applied research in turbomachinery aerodynamics, hydrodynamics and heat transfer and their application for power generation and propulsion. Research is conducted in micro gas turbines and their systems with focus on concentrated solar power applications, industrial gas turbine compressors and expanders aerodynamic performance, aeroelasticity, stability and effects of low calorific fuels on turbomachinery behaviour. Fundamental research is undertaken in turbo expanders with variable gas properties applied to organic Rankine cycles with applications in power generation using refrigerants and supercritical carbon dioxide cycles. Experimental and computational conjugate heat transfer is carried out with focus on turbine tip heat transfer. Research has been conducted in several aspects of ship propulsion focusing on performance, noise, cavitation, condition monitoring and energy savings.

People

Academic staff

Research staff and PhD students

49 researchers are currently registered as PhD students in relevant topics. During the last 5 years we have secured funding to more than 20 post-doctoral/experienced researchers, providing mentoring and career opportunities in premier academic, education or industrial institutions worldwide. Additionally, we are currently supporting the career development of at least 46 Early-Stage Researchers via the 3 Horizon 2020 Marie Skłodowska-Curie Actions ITN projects coordinated by City, through training, international and intersectoral mobility, aiming to help them to develop positive European and wider international identities and a sense of belonging.

Facilities

A number of well-equipped test cells operate in the centre. Expertise exists in flow optical and laser diagnostics, instrumentation and design. Equipment/techniques available include: RIM, LDV, PDA, SPIV, PLIF, LIEF, LE and LSD, Yag and Excimer lasers, numerous high speed cameras for shadowgraphy/Schlieren imaging, LIF-based lubricant film diagnostic system, fourier transform infrared analyser, fast-response FID Hydrocarbon, CO, CO2, and NOx analysers, transparent fuel nozzles, dynamic balancing machine for high speed shafts, high speed air motor drive (100,000 rpm), high speed motor drives (20 kW, 50,000 rpm), instrumented marine propellers and ultrasound system for erosion studies. Moreover, the Centre has exclusive use to PC clusters with more 1000cores, utilised for parallel CFD simulations.

Fuel injection test rigs

Four test cells are dedicated to research into fuel injection equipment for Diesel and gasoline internal combustion engines. City has pioneered work in this field since late ’90 under the leadership of Prof Arcoumanis. Expertise exists in manufacturing and instrumentation of real-scale optical nozzles able to withstand realistic injection pressures. Transparent nozzles offer optical access for simultaneous studies of cavitation inside the injection orifices and the near-nozzle sprays.

Enlarged scale transparent models

City is equipped with a steady-state flow circuit test rig able to provide Reynolds and cavitation numbers similar to those or real-size injectors. Enlarged transparent nozzle replicas include automotive, heavy duty and marine fuel injectors and gasoline direct injection nozzles. Capability exists for refractive index matching measurements, high speed visualisation, laser Doppler velocimetry (LDV) and stereo PIV.

Spray characterisation

High speed visualisation and laser diagnostic techniques such as DPA, LSD, LIF, LIEF and LE are available for single-droplet and spray characterisation under atmospheric or elevated air pressure/temperature conditions. Injection against pressurised nitrogen-filled CVC is available for gasoline engine applications. Fuel sprays or single droplets can be also studied upon impact on heated surfaces of various materials and different polishing. Thus, relevant studies can address a range of phenomena occurring droplet/spray impact.

The singing propeller

A method for the condition monitoring of rudders when operating in adverse cavitation conditions using acoustic emissions and Fibre Bragg Gratings has also been developed. The instrumentation has been developed for tip unloaded super yacht propellers. The technique is available and can be used at the design stage, for determining whether a propeller is likely to sing. The relevant research programme undertaken by Prof John Carlton was funded by industry.

Accelerated cavitation erosion tests (ultrasound)

The behaviour of cavitation erosion can be studied under varying conditions of material stress. Within this area of endeavour the comparative ability of protective coatings can be assessed utilising ultrasound cavitation.

Low specific speed turbocompressors

In response to a need for a turbocompressor capable of compressing low flow rates (low specific speed), a new topology was been developed, named TurboClaw. Applications include air charging for fuel cells, HVAC, steam compression, vacuum pumping, supercharging and gas compression. Successful operation of the machine has been proven in experimental tests. The machine has a superior efficiency in comparison to conventional turbocompressors operating under the same conditions and the efficiency is similar to that of positive displacement machines. It is believed that efficiency will be increased further by means of further research, particularly by application of CFD. The technology has been commercialised by Dynamic Boosting Systems Ltd.

Flywheel energy storage

Interest in electrical energy storage technologies has been growing exponentially. Flywheels are one such technology and the energy which is stored as kinetic energy is transmitted to and from the electrical supply via a high speed electric machine and electronic converter. The characteristics of this technology make it good for high C ratings (ratio of power to energy), high number of cycles and it has a calendar life of 25-30 years. It can be advantageous to operate it in a hybrid system with other storage technologies such as pumped hydro, compressed air or batteries. The initial development of the flywheel was supported for applications in automotive and rail with research partners including Nissan Motors, Tata Steel, Dynamic Boosting Systems Ltd, Turbo Power Systems Ltd and Deutsche Bahn. Innovate UK and the Rail Safety and Standards Board provided additional funding for these projects. The work at City is focussed on the safety aspects of the flywheel which has been verified experimentally in a purpose built high speed test facility and simulated in dynamic FEA.

Screw Compressor test laboratory

The screw compressor laboratory has three test rigs:

  1. Oil-injected air Screw Compressor test rig with variable frequency motor of 75kW, maximum air flow of 15 m3/min and maximum pressure up to 14 bar.
