Abstract

This paper reveals the experimentation of vertical aluminium plate on which dimples are created and arranged in the form of inline arrangement. The performance parameters of heat transfer like Nusselt number andaverage heat transfer coefficient are determined and compared. The inline dimple plates are tested for various heater inputs like 10W, 20W, 30W, 40W & 50W. Form the results, it is concluded that the inline dimple plate with 24 dimples is the best arrangement.
