The Ad Hoc Committee on Computational Heat Transfer of the Heat Transfer Division of the American Society of Mechanical Engineers has been sponsoring sessions on benchmarking computer codes. This benchmark problem is for natural convection in a square 2-D cavity containing a fluid with temperature dependent viscosity but otherwise constant properties. The vertical walls are maintained at different temperatures while the horizontal walls are adiabatic. Computational results are presented for Raleigh numbers of 10{sup 4}, 10{sup 5}, and 10{sup 6}, each on four meshes. Each grid refinement doubles the number of elements for the previous mesh in both the x- and y-directions, thereby increasing the number of nodes by a factor of four. A Galerkin finite element technique was utilized.
