摘要：
Results from an experimental study of hydrodynamics and heat transfer in turbulent separation flow under the conditions of its periodic pulsations are presented. It is found that an essential change occurs in the spatial and timing structure of separation flow under the effect of superimposed unsteadiness. Phenom- ena involving reduction of the longitudinal dimensions of the separation region and essential enhancement of heat transfer in the separation region of pulsating flow are revealed. The physical mechanism of these phe- nomena is described. © Pleiades Publishing, Inc., 2011.
