Large underground car parks require high performance of their ventilation systems, due to toxic chemicals or substances which could possibly harm humans. Jet fan ventilation systems have been employed frequently in these large underground car parks recently, as it assists, to achieve the optimal air quality of them effectively. The performance of this ventilation system, however, can be altered by the numbers of jet fans in uses and the arrangements. The aim of this study, therefore, is to estimate the performance of Jet fan ventilation systems, according to these factors. To look at 3 cases each with, differing numbers of jet fans and how the intervals between them affects overall performance. Fluent 6.0, one of the most commonly used CFD codes, is employed for the numerical analysis of this study and the results are evaluated both by case to case analysis and at each designated height level of the space. |
