| Abstract: | 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. |
