In this work a numerical study of thermal and fluid dynamics behavior of natural air convection in a square cavity in a laminar flow is presented, by finite volume method. The square cavity has two walls heated with different temperatures and two isolated walls. The numerical simulation is made up of several Rayleigh numbers to . Flow and isotherm lines are presented and analyzed. The numerical results presented in this work can be used by researchers who work in the natural convection problem.

Mixed convection is a fundamentally significant heat transfer mechanism that occurs in selection industrial and technological applications. In this study, first the laminar mixed convection inside rectangular enclosure with moving wall and Aspect Ratio=10 is modeled and then the results are compared with other investigate. After showing varity of results, the investigation is continued with turbulent flow using RNG and standard . The results indicate that the turbulence intensity depends on the position. For example, in vertical walls and boundary layer, the flow is laminar and it is in the center of enclosure turbulent.

The numerical method presented by Safaiy et al. [1] is reformulated with Finite Volume method in its most general form and tested on non-orthogonal flow problems. Navier-Stokes equations are solved for the solution of stream function and Vorticity. Numerical solutions of the driven skewed cavity flow, solved using a fine grid (513×513) mesh, are presented for Reynolds number of 100 and 1000 for skew angles ranging between . The results are compared with the numerical solutions found in the literature and also with analytical solutions as well.
