AAE Research Seminar Series - Hypersonic wind tunnels, thermochemical nonequilibrium, and spectroscopy

Abstract

High-temperature gas dynamics is important for the development of atmospheric entry vehicles and hypersonics cruisers. Various aspects of high-temperature gas-dynamics will be discussed, including the tools used to facilitate these works, the thermochemical characteristics, and the methods used to diagnose such flows. The content of this presentation contains Dr Gu’s past, presentation and future works.

Speaker

Dr Sangdi Gu received his Bachelor of Engineering in Aerospace Engineering from the University of New South Wales in Sydney, Australia. He then went to The University of Queensland in Brisbane, Australia to undertake his Doctorate. His PhD project - “Mars entry afterbody radiative heating: an experimental study of nonequilibrium CO2 expanding flow” - contributed to knowledge for designing future Mars entry vehicles. The project involved collaboration with the Aerothermodynamics branch at NASA Ames and, consequently, Dr Gu was hosted as a visiting researcher there in early 2017. After completion of his PhD in 2018, Dr Gu went to the RWTH Aachen University in Germany where he worked as a postdoc. During this time, he gave an invited presentation at the Institute of Mechanics, Chinese Academy of Sciences.
