Abstract
The Galerkin finite-element method is used in conjunction with a stream function-vorticity-temperature formulation of the steady-stale governing equations to calculate laminar two-dimensional natural convection of air within a triangular enclosure. Isosceles triangles with horizontal bases are considered. All possible combinations of cold, hot, and adiabatic walls are studied for different Grashof numbers and aspect ratios. Flow patterns and isotherms are presented. Convective Nusselt numbers are also calculated. Comparison is made with published experimental data.
