Abstract

In this
study, an experimental analysis has been performed on jet impingement onto close-cell
porous material which is the shape of a circular porous disc which is aluminum foam. This porous material was located on the circular heater and temperature distribution,
local and average Nusselt number were observed at the different situations.
Experiments were carried out by considering different parameters which are Reynolds
number (1048, 2620, 4192), the thickness
of porous disc (6, 8, 10 mm) and heater power (3.6, 6.8, 10.5 W). The results
show that the maximum average Nu number value is calculated as 464.06 at Re =
4192, P = 10.5 W. It is observed that for the lowest average Nu number value is
obtained at P = 3.6 W and Re = 1048 for without porous material. The lowest
average Nu number value is calculated as 94.201. It is found that the porous
materials can be used to control heat transfer.
