本文采用面元法和改进的数值库塔条件预报螺旋桨定常性能。
The surface panel method and an improved numerical Kutta condition have been applied to predict the hydrodynamic performance of a propeller in steady flow.
为满足库塔条件而令后缘处涡强度为零，但导致了方程组的矛盾性。
The system becomes overdetermined as zero vortex strength is set at trailing edge, to make the Kutta condition be satisfied.
