Miss Francesca Gnani, currently a research student within the Aerospace Sciences Division, under the supervision of Prof. Kontis and Dr. Zare-Behtash, has been recognised at the 30th International Symposium on Shock Waves, held in Tel Aviv, Israel, July 19-24, 2015, for her significant contribution and outstanding presentation on "Indraft Supersonic Wind Tunnel for Shock Train Investigations."

A summary of her paper is give below.

"The ability to collect accurate experimental data has allowed designers to gather valuable information in aerodynamics research and to analyse the behaviour of flows subject to varying conditions, often without building full-scale prototypes. To fulfil this need, wind tunnels that provide the working section with uniform, steady, and low-turbulence flow are essential. The study of the shock wave structure which forms in a nearly constant-area duct is particularly relevant for the prediction and control of a shock interacting with the boundary layer as it finds important application in high-speed flow devices, such as supersonic compressors, ejectors, wind-tunnel diffusers, and ramjets/scramjets inlets. The purpose of the present paper is to examine the flow physics characterising the shock wave structure which forms inside a duct along with the parameters which need to be considered in the design of an indraft supersonic wind tunnel."
