The High Enthalpy Shock Tunnel Göttingen at the German Aerospace Center (DLR) is a unique free piston-driven hypersonic tunnel in Europe and is known internationally for its requisition in various flight projects as well as fundamental investigations. Furthermore, the group of scientists, engineers and technicians have been actively developing the necessary diagnostics that accompany the challenging test environment associated with a shock tunnel. In connection to this, the HEG Group has recently started a collaboration with the University of Notre-Dame to develop Pressure Sensitive Paint (PSP) diagnostics for use in hypersonic shock tunnels.
This talk will focus on some of the recent work carried out at the HEG, with an emphasis on application of coated diagnostics used in recent investigations. The basis for the recently-started collaboration will also be elaborated.
Divek Surujhlal is a research scientist at the German Aerospace Center (DLR) in Göttingen, Germany. He competed his PhD in 2018 on experimental ínvestigations of three-dimensional shock-shock interactions. He has areas of expertise in experimental measurement techniques for hypersonic re-entry flows with a focus on shock wave boundary layer interaction and boundary layer transitional flows.
He works at the high-enthalpy shock tunnel Göttingen (HEG) and has participated in projects initiated by the US AFOSR and in several DLR projects. Further research interests include diagnostic development for non-equilibrium hypersonic re-entry flows and passive leading edge cooling technologies for hypersonic flight.
