Surrey research showcased at Turbo Expo 2016

Demonstrating its leading global position in thermo-fluid systems research, the University’s researchers were out in force at Turbo Expo 2016, presenting six papers and receiving a ‘best paper’ award.

Recognised as the world’s leading conference in this field, Turbo Expo 2016 (TE16) took place from 13 to 17 June in Seoul, South Korea – the first time it has been held in Asia. The event was staged by the ASME (American Society of Mechanical Engineers) International Gas Turbine Institute and brought together experts from around the world to share the latest in turbine technology, research and development.

During the conference, academics and researchers from the University of Surrey’s Thermo-Fluid Systems University Technology Centre presented their latest research on air flow within gas turbines – in particular aircraft engines. Based on advanced computational fluid dynamic modelling and conducted in collaboration with Rolls-Royce, this research contributes to understanding on how engines can be kept cool and operating correctly, providing valuable information for engine designers.

The papers presented at TE16 were authored jointly with colleagues at both Oxford and Cambridge Universities. The authors from Surrey included Professor John Chew and Professor Nick Hills, post-doctoral researchers Dario Amirante and Vladislav Ganine, and PhD students Sulfi Noor Mohamed, Diogo Berta Pitz and Michel Onori. In addition, the University was presented with an ASME committee Best Paper Award for a research paper presented at last year’s conference in Montreal. This research demonstrated, for the first time, how flows can successfully be predicted in compressor disc cavities – a particularly complicated air flow area in an engine.

Professor Chew, who was Technical Programme Chair at TE16, says, “We were delighted to be able to showcase some of the work we’re doing at Surrey. One of the things being investigated is the unusual and unexpected flow features which happen around the turbine rim seal.

“We identified this as an important research area in a presentation at the 2003 Turbo Expo. Interest has grown and such flows are now being investigated at several universities in Europe and North America. Our primary aim with this research is to be able to predict what the flow will be, ultimately reducing design costs and improving efficiency.”

The papers presented at the conference were: ‘Modelling of compressor drum cavities with radial inflow’, ‘Unsteady flow phenomena in turbine rim seals’, ‘Effect of bolts on flow and heat transfer in a rotor-stator disc’, ‘Les validation for a rotating cylindrical cavity with radial inflow’, ‘Direct numerical simulation of rotating cavity flows using a spectral element-Fourier method’ and ‘Aero-thermo-mechanical modelling and validation of transient effects in a high pressure turbine internal air system’.
