| 摘 要： | 同时考虑自由液面、真实螺旋桨的旋转运动,在数值水池实现了船/桨整体流场的数值计算。在既定航速下,推力与船体阻力为螺旋桨转速的函数,通过变化转速得到自航点。文中数值计算得到的自航点与物理水池试验自航点吻合良好。根据数值自航试验结果,不仅可通过积分的方法计算伴流分数与推力减额分数,还可详细分析螺旋桨进流与桨叶的速度、压力分...

| Abstract: | Flow field of the whole ship and propeller model,including free surface and propeller rotating motion,is solved in this paper.Ship self-propulsion point is derived by changing propeller rotation speed because both propeller thrust and hull resistance are the function of rotation speed.The self-propulsion point derived from numerical tank agreed well with experimental data.In numerical tank,not only wake fraction and thrust deduction fraction can be solved using integral method,but also the velocity and pres... |
