Natural convection in a model chamber with the Boussinesq approximation utilization

Journal Title: Bulletin of the Military University of Technology - Year 2017, Vol 66, Issue 3

Abstract

The paper presents numerical analysis of heat transfer inside a model chamber in time after entering an object of elevated temperature therein. As a result of the temperature difference between the object and the environment in the room, natural convection has occurred. Numerical simulations were performed using ELMER software based on the Finite Element Method. In order to reduce the complexity of the simulation, the Bussinesq approximation was used. The relevant case is similar to Rayleigh-Benard convection, which was starting point to the conducted analysis. Keywords: temperature distribution in the model room, Rayleigh-Benard convection, Bussinesq approximation
