HEAT TRANSFER IN OSCILLATING FLOW. Aeronautical Engineering Report No. 483-e, June 30, 1963

PDF Version Also Available for Download.

Description

Pressure oscillations imposed upon a compressible fluid flowing in a duct produce a substandtial increase of heat transfer between the heated duct wall and the fluid. An experimental investigation was made of the causes of this increase. Resonant conditions in a duct were used to achieve increased oscillating amplitudes. The local heat transfer incresse 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 steadystate pressure and Mach number. The presence of flow reversal further increased the observed heat transfer.
