热分层环境下船模尾流温度分布与扩展规律的试验研究

An experimentel study on the spreading and temperature distribution of a ship model’s wake in a thermal stratified flow

通过对船模在水槽中稳定热分层环境下运动后留下的尾流中的温度测量及红外摄像 ,试验研究了双螺旋桨船模在二种速度运动下 ,螺旋桨相对向内旋转、向外旋转及螺旋桨不工作时 。

In this paper, the spreading and temperature distribution of a twin-shaft screw ship molel’s wake is studied by measuring the temperature and taking infrated graphs in a thermal stratified water turnel. The ship model runs at two speeds with screws rotating in inner or outer direction as well as stopping.
