Analysis of Cross and Single Sided Naturally Ventilated Rooms Using CFD

Abstract

Natural ventilation contributes to the improvement of thermal comfort and quality conditions of the internal air, while at the same time it is recognized as a very efficient technique that, when applied properly. The present project refers to the numerical prediction of air velocities in cross and single-sided naturally ventilated rooms, which are considered along with atmospheric zone. Continuity and Momentum equations have been solved by Control Volume Method. SIMPLE and SIMPLEC algorithm are used to solve these equations. Steady, k-ε turbulence model and incompressible flow of a constant property fluid under Boussinesq’s approximation have been considered. The results are presented for both cross and single-sided naturally ventilated rooms by using Grid independence test.
