摘要
利用Fluent 6 .0软件计算和分析了船舶螺旋桨前置导管的平面流流态。比较了安装前置导管前后船体艉部流态 ,发现安装后流态发生了改变 ,旋涡大幅减少 ,流速显著增加 ,伴流不均匀性减小。用数值方法再显了现有模型试验分析的结果。
The two dimensional flow condition of the stern wake around a nozzle pre positioned of a ship propeller is calculated and analyzed by use of the software Fluent 6.0.The flow condition of the wake after the nozzle is installed is compared with the one before the nozzle is installed.From the comparison,it is found that the flow condition of the stern wake is changed,vortex is reduced greatly,flow velocity is increased remarkably and unevenness of the wake is reduced.The calculation results are verified by experimental data.
