Resumo

We study the flow of natural convection in vertical channel differentially and uniformly heated. The boundary conditions are imposed flux type. The study is based on numerical simulations using a 3D RANS turbulence model and a low-Reynolds wall treatment v2-f. The coupling between convection and radiation is considered in this study. After validating the model, the influence of external conditions (turbulence rate imposed at the input) on the temperature and velocity profiles in the channel are analyzed. The effect of key parameters such as aspect ratio, imposed wall flux, emissivity of the walls, is then discussed. Ultimately, this work aims to establish semi-empirical laws, characteristics of thermal and kinematic behavior of double-skin photovoltaic, laws that will feed a model integrated into a building environment.
