Abstract
Results of numerical analysis using Finite Volume Techniques of flow around a pyramidal structure have been reported in this paper. The conservation equations of mass and momentum have been solved in an unstructured grid by employing two equation based k-e model. The results of numerical experiments have been validated with existing results of experiments available in the literature. The apex angle and attack angle of the pyramid has been optimized for maximum reattachment distance. Similarly the apex angle and attack angle of the pyramid is also optimized for maximum turbulent intensity. From the present computation of velocity profile it is found that the back flow intensity is more at the rear side of the pyramid.
