CALCULATION OF THE FLOW IN A VENTILATED ROOM USING DIFFERENT FINITE-DIFFERENCE SCHEMES AND DIFFERENT TREATMENTS OF THE WALLS.

Author(s) : DAVIDSON L., FONTAINE J. R.

Summary

THREE DIFFERENCE SCHEMES HAVE BEEN COMPARED FOR CALCULATING THE FLOW IN A TWO DIMENSIONAL ROOM: THE STANDARD HYBRID UPWIND/CENTRAL SCHEME, THE SKEW-UPWIND SCHEME, AND THE QUICK SCHEME. IN THE STUDY NO LARGE DIFFERENCES WERE FOUND BETWEEN THE DIFFERENT SCHEMES. USUALLY WALL-FUNCTIONS ARE USED WHEN BOUNDARY CONDITIONS ARE PRESCRIBED AT WALLS, WHICH MEANS THAT THE BOUNDARY LAYERS HAVE NOT TO BE RESOLVED. AN ALTERNATIVE IS TO RESOLVE THE BOUNDARY LAYER USING A LOW-REYNOLDS NUMBER MODEL. THESE 2 ALTERNATIVES ARE COMPARED.
