METHOD FOR DETERMINING PRESSURE DROP OF AIR FLOWING THROUGH CONSTANT-AREA PASSAGES FOR ARBITRARY HEAT-INPUT DISTRIBUTIONS

摘要

A method is presented that enables convenient determination of the pressure drop sustained by air flowing at high subsonic speeds in a constant-area passage under the simultaneous influence of friction and heat addition. The method is applicable for arbitrary heat-flux distribution along the flow-passage length. Air-pressure-drop working charts based on the method developed are presented.
