    Abstract

    ![CDATA[This current paper presents the results of computational fluids dynamics (CFD) simulations of external flow over a cubic building block. The focus is given to the investigation of the domain size dependence of such simulations. This parametric study used a systematic examination of the pressure coefficient distribution around the block with stepwise variation in domain extensions in 4 directions relative to the block. The results revealed differences between the different domain expansions in each direction and the trend of a convergence. Dimensionless parameters were introduced to link the optimum domain size to the building size. The study identified the dominant direction that influences the domain dependence the most.]]
