Abstract: Hot film probes have been used to measure wall shear stress in an experimental facility designed to operate under both steady and unsteady operating conditions. Following a steady state calibration of the sensor, a full dynamic equation was used to obtain the ensemble averaged values of the shear stress in unsteady flow. The results were compared with quasi-steady values obtained using a simplified equation. A lthough the dynamic component was insignificant for the conditions analyzed, its importance is expected to increase as conditions become more unsteady.
