基于面元法的斜流中螺旋桨水动力性能
|
摘要
为对斜流中螺旋桨的水动力性能进行研究,基于低阶速度势面元法建立斜流螺旋桨水动力性能迭代计算模型,采用面元法对螺旋桨的水动力性能进行计算,并计算其在桨盘面上的诱导速度.在迭代计算过程中,根据来流速度和诱导速度对尾流进行调整,并对螺旋桨水动力性能进行重新计算,直至螺旋桨水动力收敛.实例计算结果表明,相对直流中运动的螺旋桨,斜流使得螺旋桨推力和转矩明显增加;效率在低进速条件下增加,而在高进速下降低.
In order to study the hydrodynamic performance of propeller in oblique flow,the iterative calculation model of propeller hydrodynamic performance in oblique flow was established based on low order velocity potential panel method.The hydrodynamic performance of propeller was calculated by using panel method,and the induced velocity of propeller on the disc was also calculated. During the iterative calculation process,the slipstream of propeller was adjusted according to the inflow velocity and the induced velocity,and the hydrodynamic performance of propeller was recalculated until the result converges. Example calculation result shows that the thrust and torque of the propeller is obviously increased by the oblique flow comparing with straight inflow,and efficiency increases at low advance speed and decreases at high advance speed.
