Abstract: | In an earlier note Cimbala and Park (1990) presented a method for calibrating constant temperature hot wires in incompressible gas flow which accounts for ambient temperature changes. Their method involves the retention of the temperature dependence in a form of King's Law. However, in practice the method proves difficult to implement due to a numerical difficulty in finding a best fit to the assumed functional form. This note presents a modified version of the method of Cimbala and Park which does not seem to have the numerical difficulty, as well as some further comments on the method. |
