CFD Analysis Applied to Smoke Extraction in Car Park Caused by Single Fire Source

The aim of this paper is to present the application of CFD software to the calculation and to show the image of fluid flow during garage ventilation in an emergency situation. On that way, JET fans, arranged on the ceiling of the parking lot, blow smoke at high speed, transmitting complete energy to the surrounding air. Proper arrangement of JET fans ensures that the entire air mass of the parking space gets controlled movement in the desired speed range. This reduces the pressure required by the main fans to expel and inject outside air from and into the garage space, and thus the required power of these fans. Thanks to the application of CFD analysis, a graphical representation of the flow was obtained, based on when the JET fan can be selected. In this way, the selected fans and the designed ventilation system have significant advantages over the conventional duct flue system.
