Abstract

A new theory for hot-film shear stress sensors is presented along with supporting experimental results for steady air flow. The sensor has a thick metal film (ε = 6μm) on a polymer substrate that is glued to a surface for use in a fluid flow. Numerical calculations are carried out with analysis for three bodies (air, hot film, and polymer substrate). The theory presented in this paper applies to either thin metal or thick metal films, and the heat loss through the sensor's electric leads is included. Experimental results are reported for sensors glued on plexiglass and steel surfaces in steady flows. The new theory agrees well with the experimental calibration curve.
