HypRTTC
Project: Numerical Investigations of Wall Effects on Hypersonic Transition Control
Collaborating departments: School of Engineering and Design (TUM); School of Mechanical & Mining Engineering (UQ)
The project investigates possible avenues of hypersonic boundary-layer transition control through wall effects such as localised surface heating, targeted surface roughness, suction/blowing slots or gas injection. Four PhD candidates will investigate different wall effects using state-of-the-art computer codes on highperformance computing (HPC) facilities in both Australia and Germany.
The project will address mechanisms for both transition delay, desirable on external surfaces for reduced aerodynamic drag and convective heating, and transition inducement, important for internal engine flowpaths where the laminar boundary layer is more likely to separate and cause engine unstart. One project will investigate passive control for transition control using engineered surface roughness. The second project will investigate active control using injection techniques, either blowing/suction slots or targeted gas injection. The third project will investigate active control using fine-grained surface heating patterns. The final project will investigate the use of adjoint methods for optimal transition delay/inducement.
