1. A method for locating two dimensional critical flow features on a surface of a three dimensional body immersed in a fluid stream, the method comprising:

  • applying a hot film sensor array on the surface of the body, the hot film sensor array comprising a plurality of hot film sensor elements disposable over at least a portion of the body surface in two dimensions with respect to the body surface, each sensor element being connected to an associated anemometer circuit to provide an output voltage;

    obtaining output voltage data for each hot film sensor element with the body immersed in the fluid stream under a set of flow conditions; and

    processing the hot film sensor element output voltage data to locate at least one two dimensional critical flow feature on the body surface.
