Abstract: This paper presents a computational fluid dynamics (CFD) simulation of coupled outdoor wind flow and indoor airflow in the investigation on the horizontal positions of openings on the fluctuation of cross ventilation and flow-field inside an isolated family house. Two inlet-opening positions located at the same height are used to investigate the impact of the position of windward inlet openings on the ventilation rate and flow-field inside the building. Due to unsteady flow and high turbulence near the openings, the study employed the large eddy simulation with the dynamic Smagorinsky subgrid-scale model techniques, with the CFD simulations being validated against data from available wind tunnel experiments. The study showed that the rate of ventilation through openings located near the centre of the building is higher and more steady than the flow rate of openings located near the sides of the building.
