A thermal hydraulic study of convective heat transfer in 3 3 square array of heated vertical cylinders is carried out using computational fluid dynamics (CFD). Two different CFD approaches were used, i.e., full structural details (FSD) and porous media modeling (PMM). The computational requirement in PMM declined significantly due the porous media approximation. The PMM only gives the overall flow and temperature field. In the FSD model all the geometry details are presented without any approximation. The PMM and FSD results are compared to experimental data. In general, the prediction of temperature profiles from both PMM and FSD agreed well with the experimental data.

The use of Computational Fluid Dynamics as a tool for design and analysis of aerospace systems is well established. Since the results generated by a CFD solver are numerical approximations, the solution is inherently produced with errors and uncertainties. In this paper, a simple fluid flow problem of laminar, incompressible flow past a circular cylinder at Reynolds number of 20 is allowed to be solved by the well-known finite-volume solver ANSYS Fluent. The effect of variations in mesh resolution, domain boundary location and residual criteria settings is investigated. For all the cases, finite, structured meshes of acceptable quality are used. The influence of variables on the cylinder’s drag results is analyzed and discussed. An interesting pattern in results has been observed. The study on the variation in mesh resolution showed no presence of mesh independent solution. The study on the variation of the domain distance showed that it is necessary to increase the diameter of the circle several thousand times to obtain a domain independent solution.
