Description: |
The objective of these lecture series, supported by the
Science and Technology Organization (STO-AVT-289) is 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 is introduced and discussed in
detail during this course.
The lecture series director is Dr. Fabio Pinna from the
von Karman Institute for Fluid Dynamics, Belgium.
