概要

A simplified method for simultaneous measurement of velocity and temperature of fluid flow, by using a sigle hot-wire and changing overheat-ratio rapidly, was developed. In this method, the use of concrete dimnensions and thermal properties of hot-wire, which were to get hard, was escaped, and the effect of longitudinal distribution of heat generation and the effect of the change of thermal-properties from temperature change of fluid and of overheat-ratio were taken into account in the separating procedure of velocity and temperature. The resultant accuracy of separation was about 0.12 m/s with velocity and 0.29℃ with temperature.
