Abstract

Free convection and radiation comprise the heat transfer mechanisms
through which a hydronic household radiator conveys heat from its surface to
air and surrounding surfaces. It should also be noted that their performance
could 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, were
numerically examined. To this end, radiators at two different dimensions having
two different geometric shapes were drawn and analyzed in the program Ansys 17.
The heat transfer rates obtained from the program were validated via radiator
producer catalogues. Furthermore, the influence of parameters, such as water
velocity in the radiators and thus mass flow rate, temperature difference
between water inlet and outlet and also between radiator surface and
surrounding air on convective heat transfer coefficient over radiator, were
scrutinized.
