Abstract

A building is a complex environment due to its geometry and its many stresses caused by fluctuations. Therefore the design of buildings and more specifically its thermal performance is to assist the air flow modeling of physical phenomena. In this work, we study numerically the influence of external stress (temperature) on the flow of air inside the room through a solid interface (front). The system considered consists of two circles, an internal environment that represents the local and external environment that represents the environment of the building separated by a wall. The equations governing the transient natural convection in both media, the heat transfer by convection and heat conduction in the solid wall, are discretized by the finite volume method and are solved using simple algorithm. The convective flow is governed by different control parameters, namely the Rayleigh number (Ra) and the amplitude and the period of the excitation temperature
