Abstract
In research on possible techniques for measuring wall shear stresses, a particular double hot-wire probe was designed. The working principle is to keep constant the average temperature of the two wires while the downstream one is heated by the other. The temperature difference indicates the stress while the average temperature acts as the usual hot-wire signal. The instrument was compared with other kinds of probes. It was tested under an adverse pressure gradient up to incipient flow separation
