摘　　要：使用CFD(Computational Fluid Dynamics)软件Fluent对冰下分层采水器模型采水过程中仪器内部的水体流动进行二维数值模拟。计算模拟结果显示采水器模型内的速度场、压力场等,通过Fluent后处理软件Tecplot得到采水器内部的流场图。该流场图可真实反映冰下分层采水器内部的复杂流动,在此基础上进行分析计算,可得到改进冰下分层采水器的理论依据。Computational Fluid Dynamics(CFD)software Fluent was used to conduct two-dimensional simulation of water flow inside the harvester during water harvester.The simulation results show the velocity field,pressure field and so on in the water harvester model.The flow field inside the water post-processing software Tecplot.The flow field graph can reflect the complicated flow inside the stratified water harvester under ice,on the basis of which,the theoretical basis of improving the stratified water harvester under ice can be obtained.
