摘要
Abstract
In this paper,a thermal change model with consideration of evaporation and condensation is used to descript the laws of heat and mass transfer between vapor and liquid in steam accumulators,and by combining slowly and fast charging boundary conditions,a study on the dynamic performance of marine steam accumulators during different charging modes was carried out by using the CFX code. The calculated results show that the water level fluctuated drastically at the initial period of the slowly charging process, and it stabilizes and rises at last;meanwhile, the pressure and temperature in the marine steam accumula⁃tor first rises sharply and then drops during the charging process. These calculated results are seen to agree well with the experimental data.关键词
