摘　　要：针对冬季工况下船用布风器的射流流场进行CFD数值模拟计算和风速试验,通过试验结果与模拟结果的对比发现,布风器射流流场的模拟结果和试验结果在上浮流动和贴附流动方面表现出一致性,在射流风速的衰减趋势方面吻合良好,验证CFD数值模拟方法在船舶舱室气流组织研究方面具有可靠性,为船用布风器数值模拟边界条件的设置提供参考。According to the jet flow field of marine air distributor under winter condi- tion, numerical simulation and test verification are carried out. Through the comparison of the experimental results and the simulation results, it is found that the simulation results are in good agreement with experimental results of floating and adherent jet, as well as the trends in the attenuation of jet velocity. It is proved that CFD method has the reliability in the study of the air flow in the ship＇s cabin, which provides references for setting bounda- ry conditions in simulation calculation of marine air distributor.
