Abstract:Tematika magistrske naloge je uporaba CFD orodij za analizo učinkovitosti delovanja sistemov odvoda dima in toplote. Za primer garaže dimenzij dolžine 80 m in širine 30 m sta obravnavana sistema mehanskega odvoda dima in toplote (MODT) in impulzni ventilacijski sistem (IVS). Za oba primera sta bila izdelana numerična modela, izvedena CFD simulacija ter na podlagi rezultatov primerjava. Za požarni scenarij je uporabljen požar avtomobila. Glavni spremljani parametri so bili vidljivost, delež CO, zadimljenost in temperatura. Ugotovljeno je, da oba sistema zadostujeta smernicam požarne varnosti. V obeh primerih se pojavi nekaj lokacij s povišanimi spremljanimi parametri, celovito pa se je izmed postavljenih sistemov IVS izkazal za boljšega.

Title:Comparative evaluation of mechanical smoke and heat exhaust systems in a parking garage using CFD analysis
Abstract:The topic of this master’s thesis is the use of CFD tools to analyse the effectiveness of smoke and heat exhaust systems. Two systems, a mechanical smoke and heat exhaust ventilation system (MSHEVS) and an impulse ventilation system (IVS), are investigated for a car park measuring 80 m in length and 30 m in width. Numerical models were developed for both cases, CFD simulations were performed, and the results were subsequently compared. A vehicle fire was used as the fire scenario. The main parameters monitored were visibility, CO concentration, smoke conditions, and temperature. The results showed that both systems comply with the applicable fire safety guidelines. In both cases, several locations with elevated values of the monitored parameters were identified; however, overall, the IVS proved to be the more effective of the two systems.
Keywords:Fire safety, smoke and heat exhaust, CFD, impulse ventilation system, mechanical smoke and heat exhaust
