珠海市某人防工程口部超压排风优化设计

摘要

As a case study , air distributions of three different overpressure exhaust systems in the gateway were simulated in a civil air defence work in Zhuhai City , and the optimal design scheme was found after simulation re-sults were analyzed.Simulation results show that the favorable air distribution could be obtained if air inlets and out -lets of overpressure exhaust systems in gateways were designed to stagger in vertical and horizontal directions .%针对珠海市某人防工程口部超压排风设计方案，利用CFD模拟软件对各排风方案的气流组织进行了模拟计算，并对模拟结果进行了对比和分析，得到了最优设计方案。同时模拟计算结果也表明：口部超压排风系统的送、排风口在垂直、水平方向错开布置，能得到良好的气流组织。
