**Natural convection of air in a square cavity: A bench mark numerical solution.**
*(English)*
Zbl 0538.76075

Two dimensional natural convection in a square cavity with differentially heated side walls is studied numerically. Mesh refinement and extrapolation techniques are used to improve accuracy. The governing equations are solved on a square mesh by a finite difference method, forward differences were used for the time derivatives and second order central differences were used for all space derivatives. Results obtained are given comparatively.
