Effect of the buoyancy force on natural convection in a cubical cavity with a heat source of triangular cross-section

Abstract

Numerical analysis of laminar natural convection inside a cubical cavity with a local heat source of triangular cross-section has been conducted. The mathematical model formulated in dimensionless variables such as «vector potential functions - vorticity vector» has been solved by the finite difference method of the second order accuracy. The three-dimensional temperature fields, 2D streamlines and isotherms in a wide range of the Rayleigh number from 10⁴ to 10⁶ have been presented illustrating variations of the fluid flow and heat transfer.
