EXPERIMENTAL AND NUMERICAL STUDY OF THREE-DIMENSIONAL NATURAL CONVECTION AND FREEZING IN WATER
Abstract
In this paper we describe an experimental and numerical investigation of the response of an initially isothermal fluid in a cubical box to an instantaneous cooling of the upper surface of the box. The other five surfaces are neither adiabatic nor ideal heat conductors. When the lid temperature drops below 0 °C, ice begins to form on the top wall. The onset of convection in such a problem was investigated and the effects of the ice interface on the convection are presented. The importance of the thermal boundary conditions on the flow structure is also discussed.
