Abstract

This paper presents a two-dimensional simulation of single-level fully enclosed automobile parking areas natural airflow based on a Computer Fluid Dynamic (CFD) code. For the turbulence the model k-s is used, while the conservation equations are solved with the method Simplest. The discretization of the convective terms is carried out with a hybrid scheme and the buoyancy effects are not considered. The influence of the wind in the natural ventilation is analyzed inside the design frame determined by the Italian codes. 1 Introduction In large cities, where space is at premium and the use of private
