Experimental results for convective heat transfer from a number of screen type heat storage materials, made of stainless steel and brass, were obtained by the use of the transient technique. The effects of the material, the size of mesh, and the number of screens. on the heat transfer coefficient could not be detectable A dimensionless correlation describing the convective heat transfer from the screen type heat storage materials is given in the range of Reynolds number between 60 and 1000.
