| 摘 要： | 按照库塔物理条件的基本精神,认为蒙瑞诺数值库塔条件的不足,讨论了螺旋桨面元理论不应忽略梢涡的真实存在,应该考虑尾涡强度沿流线衰减的影响,明确指出尾涡强度的衰减规律为指数衰减,具体构造了一种新的更为接近物理真实的数值库塔条件.并将这种数值库塔条件应用到螺旋桨敞水特性的数值分析中,得到一些有益的结论.

| Abstract: | Potential based low order surface panel method was used to calculate the flow field of propellers.Morino numerical Kutta condition and the pressure Kutta condition were analyzed.According to the basic meaning of the Kutta condition,the shortage of Morino numerical Kutta condition is pointed out.That the real existence of the tip vortex should not be ignored is discussed.The attenuation along streamline of the intensity of the wake vortex is considered.Point out that the law of attenuation is exponential attenuation.A new numerical kutta condition is constructed and is applied to the numerical analysis of the open water performance of the propeller.Some useful conclusions are drawed. |
