摘要

Heat transfer by natural convection, conduction and surface condensation in a fully partitioned cavity in contact with a cold external ambient through a wall of finite thickness is numerically studied. The problem formulation is based on a low-Mach number approximation in order to account for the decreases in mixture mass and average pressure within the partitioned enclosure between the initial and steady states. The heat and mass transfer with condensation are compared for various conductivity ratio of the partition wall to the fluid. It is shown that the conductivity ratio has a weak influence on the mass of water vapor condensed within the cold cell.
