摘　　要：为研究蒸汽吹扫过程中在阀门关闭时其内部的气液流动情况以及温度场变化状态,使用Ansys/FLUENT软件分析阀门内部的气液两相流和温度场的变化,以此仿真高温蒸汽排水和热传导的过程,并利用热-流-固耦合进一步分析蒸汽吹扫是否会对阀门密封性产生影响,从而探究蒸汽吹扫在解决阀门长期水下工作时海生物吸附问题,以及在低温潮湿环境下去除霜冻凝露的可行性。In order to study the gas-liquid flow and temperature field change in the valve when it is closed in the process of steam purge,Ansys/FLUENT is used to analyze the gas-liquid two-phase flow and temperature field change,and to simulate the process of high-temperature steam drainage and heat conduction.Furthermore,the thermal-fluid-structure coupling is used to further analyze whether the steam purge will have an impact on the valve sealing,and to study the feasibility of steam purge in solving the problem of marine biological adsorption when it works undersea for a long time,and in removing frost and condensation in low temperature and humid environment.
