CITY has over 100 years of experience of preparing graduates to take lead roles in industry and business and has long standing research collaborations with both commercial and non-commercial organisations. CITY attracts over 23,000 students from 156 countries, while teaching staff are drawn from nearly 50 international locations. CITY has been amongst the top 10 universities in the UK for the employment prospects of its graduates.
Since 2007 extensive facilities for testing high speed machines including gas turbine engines have been developed at CITY through a number of European Commission and Innovate UK projects. The Turbomachinery and Energy Systems Research Group forms part of the Thermo-Fluids Research Centre within the Department of Mechanical Engineering and Aeronautics, and is active in experimental and computational research in turbomachinery and their integration with energy and transport systems. Primarily this includes fundamental studies on turbomachinery aerodynamic performance, with application areas including gas turbines fired using alternative fuels, micro gas turbines, organic Rankine cycles and supercritical CO2 cycles. CITY staff have over 100 publications in relevant areas of research and development in turbomachinery, gas turbines, micro gas turbines, organic Rankine cycles, high speed electrical machines and drive electronics.
MAIN TASKS IN PROJECT
CITY’s contribution to the project focuses on the following areas together with Exergy:
1. Leader of the Turbomachinery Design Work Package (WP3).
2. Preliminary sizing of the turbine and expander to enable initial cycle analyses.
3. Aerodynamic design and optimisation of an axial flow expander for a full-size plant.
4. Turbine and pump performance characterisation when operating with different sCO2 blends.
5. Turbomachinery cost assessment enabling accurate cost assessment of the full-size plant.
6. Involvement with the dissemination and exploitation of the project results.
DESCRIPTION OF ANY SIGNIFICANT INFRASTRUCTURE AND/OR ANY MAJOR ITEMS OF TECHNICAL EQUIPMENT, RELEVANT TO THE PROPOSED WORK
CITY has extensive facilities for computational and experimental research focused on turbomachinery. This includes a high-performance computing cluster, an in-house CFD and aeroelasticity code (SURF), and inhouse design tools for the design of turbines operating within non-ideal working fluids. Furthermore, CITY has a test facility for micro gas-turbines, and are currently developing a closed-loop wind tunnel for studying high-speed flows of organic fluids. Experience in these areas will be used to help undertake the and validate the turbomachinery design and characterization work.
