Investigation of flow turning phenomenon - Effects of frequency and blowing rate
Abstract
A numerical investigation of acoustic wave propagation in a simulated solid propellant rocket combustor is described. Particular attention is given to the effects of variation of the propagating direction, acoustic wave frequency, and the blowing rate through the lateral boundary on acoustic energy dissipation, streaming effects, and the acoustic flow field near the injection surface. The time-averaged axial energy flux values were integrated over radial planes to calculate the axial dissipation of acoustic energy as the wave propagated over the injection zone.
