Three-dimensional numerical simulation of turbulent flow around buildings using the k−ε turbulence model
AbstractThree-dimensional numerical simulations of air flow around a cubic model and building complex using the k−ε two equation turbulence model are presented in this paper. Several cases of numerical simulation of airflow around a cubic model are carried out to estimate the influences of a mesh dividing system and boundary conditions on simulated results. The accuracy of these simulations is examined by comparing the predicted results with wind tunnel experiments conducted by the authors. It is confirmed that numerical simulations by means of the k−ε model reproduce the velocity and pressure fields well when using fine mesh resolution around the model. In the latter half of this paper, the numerical method is applied in order to predict the flow field around a building complex under construction at present. The applicability of the numerical method in practical situations is demonstrated.
