深海载人平台密闭舱室气流组织数值模拟

Numerical Simulation of Air Distribution of Hermetic Cabin in Deep Sea Manned Platform

基于计算流体力学方法,采用Fluent软件对深海载人平台密闭舱室气流组织进行数值模拟,分析不同气流组织形式下舱内空气温度和速度的分布规律,结果表明:在舱室热源较大且分布不均的特殊条件下,双侧外送风气流组织形式不能满足要求;采取分布散流器送风形式时,平送风与下送风相结合的形式优于单纯采取平送风或下送风形式。

Based on CFD,the numerical simulation of air distribution of hermetic cabin in deep sea manned platform is carried out by Fluent.The temperature and velocity distribution law of cabin air of different air distribution forms are analyzed.The results show that under the special conditions of large heat source and uneven distribution,the organization of the double-side external airflow cannot meet the requirements;when the distributed diffuser is used,the combination of parallel and vertical air supply is better than parallel air supply or vertical air supply.
