Multiphysics Phenomena Analysis on Boundary Layer Stability in Hypersonic Regime


The objective of AVT-289 Special Course on “Multiphysics Phenomena Analysis on Boundary Layer Stability in Hypersonic Regime” was to complement the field of high speed fluid dynamics and laminar-to-turbulent transition. Gas surface interaction, ablation and complex chemical reactions strongly influence the high speed flow field and its stability. Future investigations and design techniques shall consider these coupled phenomena. It has already been experienced in real flight tests that surface roughness and ‘transpiration’ type gas flows introduced through the surface of the vehicle do not lead, in all cases, to a complete laminar/turbulent transition. Especially the gas flow that is generated usually by pyrolysis of the ablative surface is characterized by such a low velocity that its effect is usually neglected. On the other hand chemical reactions have a strong impact and selection of the appropriate modeling has a relevant effect of the simulation of the flow stability. Theoretical and experimental modeling of the effects of hypersonic flows on transition along surface roughness and surface-normal low speed gas blowing into the boundary layer was introduced and discussed in detail during this course.
