| 摘 要： | 通过求解雷诺时均的RANS方程数值模拟了单独喷水推进器和螺旋桨的流场,并用试验数据验证了数值计算的结果。在得到满意的结果之后,数值模拟了一台喷水推进器与两个螺旋桨混合推进系统的流场。通过流线和压力分布等研究混合推进系统流场特点。混合推进系统中,喷水推进器与螺旋桨的进、出流条件都发生了的改变,其中螺旋桨的改变较大。不同螺旋桨旋向计算结果表明,外旋桨有助于改善混合推进系统中喷水推进器的进流、提高整个推进系统的效率。数值计算和理论分析都表明,混合推进系统中,螺旋桨性能对流场的变化更敏感,在设计时应给予更多的关注。

| Abstract: | Flow fields of an isolated waterjet propulsion system and an open-water propeller are simulated by solving RANS equations and results are validated by experimental data.After satisfying results are derived,flow field of a hybrid propulsion system with a waterjet and two propellers is simulated.The characteristics of hybrid propulsion are researched according to streamline and pressure distribution.Inflow and outflow conditions of two propulsors are changed and the conditions of propellers are changed more w... |
