Numerical simulation of a natural ventilation case

Abstract

A numerical scheme to simulate the flow patterns promoted inside buildings by the combined action of natural wind and heat release is presented. The problem of the natural ventilation of a low-rise building with a two­water roof in communication with the outside envirorunent through two small ventilation openíngs, for a typical situation of mixed convection is considered. The results obtained from the numerical simulation performed for this situation are presented and discussed.
