HEAT FLUX JUMP METHOD AS A POSSIBILITY OF CONTACTLESS MEASUREMENT OF LOCAL HEAT TRANSFER COEFFICIENTS

Popis výsledku v původním jazyce

This article deals with the derivation of the temperature response of the finite thickness wall, which is heated by heat flow, as a possibility to measure the local values of the heat transfer coefficient with a very high spatial resolution. In addition to its own experimental measurement technique, it is also possible to use this derivation to describe the gradual heating of the wall while using the temperature oscillation (TOIRT) method for the heat transfer measurement. The system of the partial differential equations and the boundary and initial conditions is solved by a transformation into Laplace’s space, where the task is easier to solve. At the end of the article, the results of the analytical solution are compared with a numerical solution of this problem.
