Abstract

A modelling of indoor air flow and heat transfer through door and window by free convection Guang-Fa Yao, J.A. Khan Department of Mechanical Engineering, University of South Carolina, Columbia, South Carolina 29208, USA ABSTRACT In the present work, an investigation of natural convection in partitioned enclosure is made. The effects of following parameters on convection transport were studied; (1) Enclosure aspect ratios A^=L/H; (2) Aperture ratios Ap=h/H; (3) Rayleigh numbers. Parametric study is made for two hundred different cases. This work is significantly different from similar numerical works because we studied the flow at higher Rayleigh numbers than were studied previously. Both the heat transfer and fluid exchange rates through the opening in the partition are studied. The knowledge of volume exchange and heat transfer rates can be directed toward modelling the contaminant transport in buildings and indoor air quality study. INTRODUCTION In or
