CONJUGATE NATURAL CONVECTION IN AN ENCLOSURE WITH LOCAL HEAT SOURCES
摘要
The development of unsteady conjugate natural convection in an enclosure has been numerically studied. The decision region is common in many applications, such as environmental control (e.g., room), applied chemistry (e.g., storage reservoir), and electronics (e.g., cabinets). The enclosure considered has thick walls, two heat sources, and a zone with an elevated heat transfer intensity. The heat sources are isothermal. The governing unsteady, three-dimensional heat transfer equations, written in dimensionless terms of the vorticity vector, vector potential functions, and temperature, have been solved using an implicit finite-difference method. The conjugate heat transfer in the enclosure is investigated by means of a continuum model, which treats the fluid and solid constituents individually. The solution has the following parameters: the Grashof number Gr and the Prandtl number Pr. Results have been obtained for a Prandtl number of 0.702 and Grashof number ranged from 104 to 107.
