On Temperature and Yaw Dependence of Hot-Wires.

Pagination or Media Count:
A scheme utilizing a temperature probe immersed in the working fluid to compensate for the dependence of hot-wire velocity calibration on ambient temperature variations was analyzed. One needs only to know the properties of the anemometer bridge and the velocity and temperature probes to achieve the compensation. Hence the scheme provides means for incorporating the temperature compensation a priori to conducting the experiments without any need for temperature calibration.
