DETERMINATION OF THE TEMPERATURE DISTRIBUTION THE PERFORATED FINS UNDER

摘要: This work treats the problem of heat transfer for perforated fins under natural convection. The temperature distribution is examined an array rectangular (15 fins) with uniform cross-sectional area (100x270 mm) embedded various vertical body perforations that extend through fin thickness. patterns include 18 circular (holes). Experiments were carried out in experimental facility was specifically design and constructed this purpose. rate coefficient increases perforation diameter increased.
