Abstract
Synthetic jets are a promising means of the active control of internal flows in units of turbojet (TJ) engines. They reduce or eliminate separation zones which can arise in flows in transition ducts between engine elements and diminish the nonuniformity in the parameter distributions at their exits. This becomes actual for aircraft TJs in view of the tendency to reduce the dimensions of adapting diffusers between engine elements. In this study, the effect of synthetic jets on separation flow in an S-shaped diffuser is numerically investigated using a high-resolution RANS/ILES method. The results of a parametric investigation of the effect of the regime parameters of the synthetic jets and the Reynolds number and the temperature at the diffuser entry on the synthetic jet efficiency are presented.
