Abstract
This paper investigates the phenomenon of natural convection in an enclosure, fitted with completely vertical partition. The vertical wall is parallel to the two vertical isothermal enclosure walls, which are maintained at different temperatures, while the horizontal walls of the enclosure are adiabatic. The impermeable partition, separating two fluid reservoirs, is considered to transfer heat between two subenclosure. The governing equations for stream
fun~tion, vorticity, and energy are solved with the aid of cubic spline collocation method. Parametric studies of the effects of the partition on the fluid flow and temperature fields in enclosure have been performed. Results show that the properties and locations of partition and Rayleigh number have a significant influence on the flow and heat transfer characteristics.
