VKI Lecture Series STO-AVT-235 on Flow Characterization and Modeling of Hypersonic Wind Tunnels


Experiments in hypersonic ground facilities represent a key pillar, alongside theoretical models and numerical computations, for all space application programs. Successful investigations in these high-speed wind tunnels strongly depend on the quality of the flow testing conditions and on their characterization.

This special course will present the different types of hypersonic wind tunnels addressing their operating principles as well as their capabilities and limitations with the flow physics specific to such ground testing facilities (flow establishment, pollution, condensation, real gas effects...).

The lectures will focus on flow characterization methodologies covering intrusive and non-intrusive measurement techniques dedicated to low and high enthalpy facilities. They will expose how specific flow conditions, such as dense gas and high temperature effects, can be accounted for during the rebuilding of free-stream flow conditions. It will be shown how flow diagnostics with appropriated data processing need to be combined with numerical modeling to better understand high speed flow phenomena. It will also show how numerical modeling can improve the understanding of ground facilities and will lead to examine non-equilibrium flow expansions as well as the main challenges in hypersonic testing for today's aerospace research and applications.

This lecture series is designed to be a meeting with specialists for researchers on aerospace engineering, hypersonic testing, flow diagnostics and high speed flows modeling to discuss operation, characterization and applications of hypersonic wind tunnels for aerospace missions.
