As the flow through a cascade should satisfy the Kutta condition and blades have generally a finite thickness at their trailing edge, it has been difficult to realize computationally the Kutta condition in the present finite element methods. In this paper, a method to realize the Kutta condition is proposed by making the pressures on the pressure-and the suction-sides of the trailing edges equal, and by expressing the blade and small separation region postulated behind it with spline-fit curves. The resultant slip factor gives almost the same value as that proposed by Wiesner or Stodola, and the calculated pressure distributions around the blade show a good agreement with measurements.
