CFD Analysis of Smoke and Temperature Control System of Car Park Area with Jet Fans

Abstract

Basements of hospitals are generally used as indoor parking area.  When underground car parks are examined physically, it is not possible to ventilate them by natural roads. Therefore, in order to keep the density of harmful gases below certain limits; ventilation systems must be used. In this study, for a parking lot with a closed area of 19438.59 m²; jet fan system is designed and the performance of the system is simulated with Computational Fluid Dynamics (CFD). The covered parking area examined is located in Isparta; It is located on the 2nd basement of Isparta City Hospital.  The parking area is divided into 5 zones and CFD smoke analysis is made for the jet fan ventilation system designed for the parking area. The purpose of this study in Isparta City Hospital (basement-2) to examine the ventilation system is designed for parking areas using CFD.  The CFD analysis made allowed us to see the correct placement of the jet fans and to decide the best placement. In case of a fire, various scenarios were prepared in accordance with international standards and the best results were obtained.
