HEAT TRANSFER IN OSCILLATING FLOW.

Abstract

Pressure oscillations imposed upon a compressible fluid flowing in a duct produce a substantial increase of heat transfer between the heated duct wall and the fluid. This report records an experimental investigation of the causes of this increase. Resonant conditions in a duct were used to achieve increased oscillating amplitudes. The local heat transfer increase was found to be highly dependent on the amplitude of the local velocity oscillations, and to depend also on the frequency of oscillations and the duct steady-state pressure and Mach number. The presence of flow reversal further increased the observed heat transfer. (Author)
