Abstract

A forced convection heat transfer experiment was conducted to study the heat transfer from hot rectangular flat plate ( 155 x 115mm ) to an air stream. The hot plate was situated between unheated plates array at various locations in the flow direction. The study was mainly concerned with the effect of the plate location on the average film coefficient of the transfer. An experimental test rig was designed and constructed for this investigation. The experiments covered the plate locations of x= 12.5, 22.5, 32.
5, 42.5 and 62.5mm, and extended over a range of Revonolds number from about 6,680 to 107, 170. A correlation between the average Nusselt number, the Reynodls number and the hot plate dimensionless location (X) was deduced. The experiments were performed for the case of uniform heat flux. A comparison with the available work in the literature review was also made.
