A Device for Measuring the Heat Flux on the Cylinder Outer Surface in a Cross-flow

The paper presents heat transfer measurements results concerning a cylindrical element. The cylindrical rod that is the object of interest that is surrounded by a mixing region of hot and cold flows and, as a consequence, is subjected to thermal device for determining heat flux on the outer surface of fluctuations. The paper describes an experimental he rod, the method is based on the solution of the inverse heat conduction problem (IHCP). A heat flux measuring instrument is described together with its construction and tests performed at a special design stand.
