Summary

The effects of aspect ratio, Prandtl number, and thermal conductivities of fins on two-dimensional unsteady laminar natural convection in a rectangular cell surrounded by a vertical hot wall, a vertical insulated wall, and two horizontal conducting fins have been studied numerically using the SIMPLER algorithm. Transient velocity and temperature distribution, and timewise variation of the average Nusselt number on the hot wall are compared with those for a cell with nonconducting fins.
