Abstract
In this study, the thermal behaviour of residential buildings with cantilever beam underwinter boundary conditions was numerically investigated by means of the open-endedstructure approach. For this purpose, parametric studies were carried out for various ratiosof cantilever beam depth/cantilever beam height (d/H) and Rayleigh numbers using a computerprogram for no wind laminar flow conditions. Analyses were conducted for Rayleighnumbers in the range of 103 to 106. The calculations were carried out for the ratios of d/H,namely 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0. The working fluid was treated as air (Pr=0.71). Accordingto the findings, the mean Nu number along with the outer vertical wall (surfaceL) of the residential building, in general, decreases as d/H increases. This decrease in themean Nu number is evident for Ra≤104, but it appears to be more pronounced after Ra=105.To have minimum heat loss from a residential building under winter day boundary conditions,it is suggested that the ratio of d/H should be between 0.2 and 0.5.
