METHOD AND SYSTEM FOR LOCATING CRITICAL FLOW FEATURE INDICATORS

摘要

A method for locating two dimensional critical flow" features on a surface of a three dimensional body imersed in a fluid stream is presented The method comprises applying a hot film sensor array (212) on the surface of the body The hot film sensor array comprises a plurality of hot film sensor elements (214) disposable in a two dimensional array over at least a portion of the body surface Each sensor element is connected to an associated anemometer circuit (222) to provide an output voltage.
