Abstract

This paper presents results of CFD simulations of flow around and through a cubic building with symmetric openings on two opposite sides.  The case where the incoming wind is perpendicular to the front face of the building, and so parallel to the openings, is considered.  An unsteady method, Detached Eddy Simulation, is used to capture the unsteady cross-ventilation.

Key words:  CFD, cross flow, model selection, turbulence models, steady state, transient.
