The Study of Parametric Factor in Attic Space for Winter Season

Abstract

Abstract This research investigates the structure of an attic space from the perspective of thermal engineering. It helps in understanding the variation of flow and field strength due to natural convection. A critical review concludes that heat transfer inside a building is most complex for the attic space. The study examines the effect of the parametric factor on natural convection. It includes analysis for the winter conditions. The numerical model is simulated for different values of Rayleigh Number (Ra = 104 − 106) using ANSYS 19 considering air with Prandtl number 0.71. With the assumptions of having the uniform temperature over the wall and no-slip condition for walls, Results are demonstrated with the use of Isotherm, Streamline and Nusselt number. With the finding of plots, the study argues that S/L ratio of 0.8 is recommended for the attic space having good thermal performance.
