Abstract

Nano-tracer Planar Laser Scattering (NPLS) technique and pseudo-color processing technology are employed to investigate the flow field after a thickness plate of non-isobaric initial conditions. The results show that the supersonic mixing layer behind the blunt trailing edge will deflect toward the low pressure side which is consistent with the canonical mixing layer. However, there is no laminar region for any unmatched cases and the turbulent state of the mixing layer seems to be restricted for the case of the low-speed side with a higher pressure.
