Abstract

High maneuverability has been a major performance index bf modern military combat flight. Thus, the avionics installed on the flight will frequently suffer the effects of acceleration. The flow and heat dissipation performance of avionics heat Bink will be affected by the super gravity environment. In order to clarify the effects of acceleration, simulative accelerating experiments of flow and heat transfer performance in straight microchannel with rectangular cross section have been conducted. A test piece made of copper is machined. FC-72 is taken as coolant. Simulative accelerating equipment is set up, on which the test piece is installed. Several different acceleration conditions are applied in the experiment. The resulting centripetal acceleration ranged from Og to 15g. Tests are ponducted by varying heat load, flow flux, and microchannel orientation relative to the direction of the accelerating force. In this study, new experimental data is presented. The flow and heat transfer performance in straight microchannel under the effects of acceleration is analyzed. The result shows that the directions and amplitudes of the acceleration have great effects on flow and heat transfer performance in the channel.
