摘要
根据势流方法建立求解螺旋桨表面偶极强度的积分方程,用离散方法求解该方程,螺旋桨表面的源汇强度可以根据运动学边界条件得到.根据已知的源汇强度和偶极强度,求解螺旋桨的诱导速度,进而计算螺旋桨尾流场中舵表面的源汇强度和偶极强度.根据舵表面的源汇强度和偶极强度,计算舵的诱导流场及其对螺旋桨的影响.由于螺旋桨和舵之间存在相互影响,因此在研究中需要有一个迭代计算过程.迭代计算收敛时即可得到螺旋桨和舵的诱导流场.根据数值方法编制了计算程序,并用该程序研究了舵对螺旋桨尾流场的影响.
The integral equation of dipole intensity on propeller surface is established according to potential flow method.Then this equation was solved by using discrete method.Source-sink intensity on propeller surface might be calculated by kinematic boundary conditions.According to the known intensity of source-sink and dipole,induced velocity of propeller was solved;further mentioned above intensity of rudder surface in flow field behind propeller was calculated.According to intensity of source-sink and dipole on rudder surface,the flow field induced by rudder and the effect of rudder on propeller was calculated.As a result of the interaction between propeller and rudder,there needed to be a process of iterative.When iterative calculation was convergent,the flow field induced by propeller and rudder could be gained.This article programmed a calculation program according to numerical method.The effect of rudder on flow field behind propellers was also studied by this program.
