Flow Dominating Instability in Supersonic Flows
The shock-induced separation is a common phenomenon in supersonic combustion, especially when the scramjet combustor works under high equivalence ratios. The low-speed recirculation zone and strong heat releas...

Flame Flashback in Supersonic Flows
Non-stationary flame propagation against the incoming supersonic flow in scramjet engines has been in focus of numerous experimental and computational studies. In this chapter, we give the research work of the...

Acoustic Oscillation in Supersonic Combustor
In the supersonic combustors, there exist intense exothermic reactions between fuel and oxidizer. In many cases the combustor does not work as expected, where the pressure oscillations occur, especially for th...

Flame Behaviors Near Blowoff in Supersonic Flows
Blowoff limits, including rich blowoff limit (RBO) and lean blowoff limit (LBO), are the boundaries between stable combustion and flame blowoff. The blowoff limits usually depend on the conditions of inflow, f...
