Abstract

In this study, a three-dimensional numerical simulation of airflow around a cubic model using the k-ε{lunate} two-equation turbulence model (hereafter abbreviated as the k-ε{lunate} model) is investigated. Results of numerical simulation of airflow around a building model are affected by many factors. Seven cases of numerical simulation of airflow around a cubic model were investigated in order to estimate the influence 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 simulation using the k-ε{lunate} model accurately reproduces the velocity and pressure fields witha fine-mesh resolution around the model.
