Abstract

An experimental study was made of unsteady heat transfer of conduction in a disk and forced convection between an impinging jet of water and the disk. Temperature changes with time at two points in the disk depended upon its dimensions, diameter of a cylindrical nozzle and average velocity of water in the nozzle. The heat flux in the vertical direction at the interface between the fluid and the disk depended upon the local radius of the disk. These experimental results are expressed by a heat transfer model. An empirical equation of the heat transfer coefficient is presented.
