Etude numérique des transferts thermiques couplés dans une cavité fermée

Abstract

In the present work, a numerical simulation based on finite differences is proposed, to study the thermal stratification evolution and the dynamic behavior of a fluid in a closed cavity. To process the radiative exchanges between surfaces in the enclosure, a radiosity method is proposed for calculating view factors, vector radiosity, and the radiative flux. The mathematical model combines the two algorithms related to the two phenomena mentioned above. The main objective of this study is the implementation of a numerical code simulating a coupled natural convection and radiation in a laterally heated 2D cavity.
