摘要
方舱空调风道的改进设计可以提升出风的均匀性.建立了某型指挥中心方舱风道的仿真模型,对风道内部流场进行了仿真分析,结合风道流场的仿真结果与经验设计对风道截面突变处采用圆角过渡优化处理.仿真结果表明:优化后的风道弯道处回流区基本消失,风道内流场均匀性得到提高,风道出风口均匀性得到明显改善,方舱的舒适性得到提升.
Abstract
The improved design of shelter air conditioning duct can improve the uniformity of air output.In this paper,a simulation model of a command center's sheltered air duct is established,and the flow field inside the duct is simulated and analyzed.Combined with the simulation results and empirical design,the round-corner transition optimization is applied to the abrupt change of the air duct section.The simulation results show that the return area at the bend of the optimized air duct basically disappears,the uniformity of the flow field in the air duct is improved,the uniformity of the air duct outlet is obviously improved,and the comfort of the shelter is improved.
