Heat transfer coefficient measurements using Infrared Thermography technique

The measurement and modeling of surfaces temperature at the impact with fluid jet is of great importance for many engineering applications. The goal of the present study is to develop an experimental procedure to determine the convection heat transfer coefficients in natural and forced flows in the vicinity of a vertical surface. An infrared camera FLIR Therma-Cam SC 3000 is used for the surface temperature evaluation, in parallel with the temperature measurements using a set of thermocouples. A vertical electrically heated disk will be the configuration for this study. A cold air jet is directed perpendicular to the surface, the corresponding Reynolds number and the distance from the wall being changed in order to investigate their influence on the measured heat transfer coefficient.
