Simulation and optimization research on the induced ventilation system in Peacetime of civil air defense underground garage combined with peacetime and wartime

Civil air defense construction advocates the combination of peacetime and wartime. Under this background, according to needs civil planning, many underground garages take into account requirements projects in their construction. The ventilation system garage combined with wartime is related quality safety masking personnel evaluation optimization performance very important. In Peace Age, works more peacetime. This paper takes an Jinan, Shandong Province as research object. By using computational fluid dynamics (CFD) technology actual working conditions peacetime, numerical simulation airflow organization pollutant CO concentration field during ductless induced carried out, distribution characteristics velocity field, temperature are analyzed. results show that optimized can effectively dilute discharge other pollutants play a good effect, make uniform, achieving purpose improving optimizing garage. As result it has promotion prospect.
