Description
Summary:In thisstudy, an experimental analysis has been performed on jet impingement onto close-cellporous 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 Reynoldsnumber (1048, 2620, 4192), the thicknessof porous disc (6, 8, 10 mm) and heater power (3.6, 6.8, 10.5 W). The resultsshow 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 isobtained at P = 3.6 W and Re = 1048 for without porous material. The lowestaverage Nu number value is calculated as 94.201. It is found that the porousmaterials can be used to control heat transfer.
