Numerical modeling and mathematics of Building Energy Rating

Résumé

The main objective of this study is to determine the quality of the heat transfer and the quality of the water.The physical problem is governed by the equations of continuity, momentum and energy. These governing equations are written in terms of primitive variables and are recast into a general form considering the hypothesis of Boussinesq.Generally, these equations do not admit analytical solutions, so recourse to numerical methods appears mandatory. We opted for the method of "Runge-Kutta". The results of this work are presented in the following table.

Keywords. Optimizing energy efficiency of housing, The method of "Runge-Kutta, Numerical methods, Numerical modeling and mathematics of Building Energy Rating.
