LARGE EDDY SIMULATION OF NATURAL CONVECTION BOUNDARY LAYER ON A CYLINDER
Paper i proceeding, 2005

Large eddy simulation of natural convection boundary layer along a constant temperature vertical cylinder is studied and the results are compared with the existing experimental data. The highest local Grashof number is Gr_z=5*10^{11}. It is shown that although there are some discrepancies between the results in the region close to the wall, there is qualitative agreement between them. In order to verify the credibility of the simulations, cross correlation of Reynolds stresses is studied and interpreted.
