Popis: The response of inclined hot wires operated in the constant wire temperature mode to fluid temperature variations was explored experimentally over a range of incident angles from 5 degrees to 85 degrees . Results showed that the square of the output voltage varied linearly with fluid temperature as reported previously for wires normal to the flow. The slope of the plots of voltage squared against temperature was found to be a function of the effective velocity only, thus allowing implementation of a simple, instantaneous temperature compensation technique. An additional benefit of the method is that it can detect faulty wires.
