The study of spatial configuration and characteristics of pulsed-wire velocity probe shows that: the yaw-and pitch-response characteristics have a good behavior due to the asymmetrical arrangement of the prongs. Because the amplitude of sensor wire response signal changes with the flow velocity, the differentiated signal is selected to trigger a voltage comparator. The pulsing frequency is restricted to about 100Hz to allow the wire to cool between pulses. The first velocity probe with big acceptance cone has been developed in China, and the way of measuring the Reynolds normal and shear stress and application have been given in this dissertation.
