To develop reliable computer models for the bluff body flow and transport of pollutants or chemical and biological (CB) agents in urban environments requires accurate measurements of the basic flow fields for carefully controlled, well-known conditions. Fluid modeling in an Industrial Wind Tunnel provides an opportunity to produce accurate simulations of the bluff body flow and transport of urb...

The purpose of this paper is to explain the attractive applicability of the advanced vortex element methods and their contribution to the beginning of the new generation of CFD, with introduction of epoch-making application of the methods to simulation of unsteady flows around bluff bodies and virtual operation of fluid machinery. The vortex methods have been developed and applied for analysis ...

The focus of presented numerical study is to investigate the effect of Reynolds number with respect to both heat transfer and flow characteristics in a channel equipped with two triangular bluff bodies in side by side arrangement. (SST) k turbulence model is used for simulations and the second order upwind numerical scheme and SIMPLE (pressure implicit with splitting of operations) algorithm a...

By combining a wavelet-based grid adaptation strategy with the Brinkman penalization technique an efficient numerical method to simulate turbulent flow past bluff bodies is obtained. The approach is very promising for the simulation of turbulent flows of scientific and engineering interest. To demonstrate the feasibility of the method some preliminary numerical experiments are conducted for flo...
