HEAT TRANSFER AND MOISTURE LOSS FROM F ROZEN SURFACE - AN ENGINEERING APPROACH

Abstract

This paper presents an analysis of convective heat load of frozen surfaces. A mathematical model for determination of "dry" and "wet" heat loads has been formed. The mass heat transfer coefficient σ i s estimated by the Chilton -Colburn's analogy . T he impact of re levant parameters of convective loads (flow velocity and relative humidity over ice, the surface temperature of the ice rink and the characteristic length of ice rink ) has been analyzed . Finally, measures for improv ing the energy efficiency of the system has been highlighted
