Summary
Front separation flows supported by an upstream energy deposition are examined. It is shown that a reason for separation region formation is an interaction of a thin high temperature wake (“thermal spike”) which is formed downstream a localized energy deposition region with a shock layer upstream of a body. Some simplified analytical models are applied to describe a front separation phenomenon. To realize steady flows with isobaric front separation regions in numerical experiments the “method of transformation of energy deposition” is proposed. The method is applied for both blunt as well as streamlined “thermal spiked” bodies to realize conical front separation regions. “Shock-free” separation flows initiated by subsonic “thermal spikes” are particularly examined.
