Hermann F. Fasel

About

Hermann F. Fasel is a Professor of Aerospace and Mechanical Engineering and a member of the Graduate Faculty at the University of Arizona. His research focuses on high-speed boundary-layer instabilities, laminar-turbulent transition, and flow control in hypersonic flows. Fasel has contributed to the understanding of nonlinear transition stages in high enthalpy and hypersonic boundary layers, utilizing advanced computational tools such as direct numerical simulations and high-order-accurate flow solvers. His work includes investigations into boundary-layer stability, shock-wave interactions, and the development of transition prediction models for hypersonic flow regimes. Throughout his career, Fasel has been involved in numerous experimental and numerical studies related to flow phenomena relevant to high-speed aerodynamics. He has received recognition for his contributions to fluid dynamics, including being named an AIAA Fellow and receiving the AIAA Fluid Dynamics Award. His research aims to improve the understanding of flow stability and transition mechanisms in high-speed flows, which are critical for the design of hypersonic vehicles and aerospace applications.

  Senior authorCorresponding

  Direct numerical simulations were carried out for a straight and a flared cone at Mach 6 and zero angle of attack to investigate the effects of geometry on the linear and nonlinear stages of the laminar–turbulent transition process. The cone geometries and the flow conditions of the simulations are chosen to closely match those of the experiments conducted at the Boeing/AFOSR Mach 6 Quiet Tunnel (BAM6QT) at Purdue University. In the linear (primary) instability regime the flared cone resulted in…

• Transition delay in a Mach 6 boundary layer using steady blowing and suction strips

  Journal of Fluid Mechanics · 2024-07-25 · 9 citations

  articleOpen accessSenior author

  Direct numerical simulations (DNS) were carried out to investigate flow control for transition delay using steady blowing/suction strips at the wall of a flared cone at Mach 6 and zero angle of attack. For the numerical investigations of the transition control strategy, the flared cone geometry and the flow conditions of the experiments in the Boeing/Air Force Office of Scientific Research (AFOSR) Mach 6 Quiet Tunnel (BAM6QT) at Purdue University were chosen. For the DNS, transition was initiate…
