DETERMINATION OF SOM E DOMESTIC RADIATORS’ THERMAL CAPACITY NUMERICALLY

Öz:

Free convection and radiation comprise the heat transfer mechanisms through which a hydronic householdradiator co nveys heat from its surface to air and surrounding surfaces. It should also be noted that their performancecould be enhanced by improving surface geometries as well as increasing temperature levels. In the present study,heat transfer rates and convective heat transfer coefficients occurring through the investigated radiators, werenumerically examined. To this end, radiators at two different dimensions having two different geometric shapes weredrawn and analyzed in the program Ansys 17. The heat transfer rates obtained from the program were validated viaradiator producer catalogues. Furthermore, the influence of parameters, such as water velocity in the radiators andthus mass flow rate, temperature difference between water inlet and outlet and also betw een radiator surface andsurrounding air on convective heat transfer coefficient over radiator, were scrutinized.
