| 摘 要： | 对42 m拖网渔船设计了导管螺旋桨,利用FLUENT软件计算其敞水水动力性能。在保持螺旋桨形状不变的情况下,改变导管的长径比、收缩系数和伸张系数三个形状参数,分别计算并比较它们的敞水水动力性能,进而研究导管参数对整个推进器推进效果的影响规律。

| Abstract: | This paper designed a ducted performance by FLUENT. With constant with three changeable shape parameters propeller for a 42 m trawler, and calculated its open water hydrodynamic propeller shape,the open water hydrodynamic performance are calculated of the ducted propeller,i.e, length-diameter ratio, shrink coefficients and stretching coefficients of the ducted propeller. The influence of these parameters of duct on the propulsion effect of the whole thruster is then studied by comparing the calculation results. |
