The cavitation minimization of the waterjet inlet is an important matter in designing the inlet configuration for high speed SES (Surface Effect Ship). For this purpose it is necessary to know the pressures on the inlet surface. However it takes much effort to calculate the pressure distribution in 3-D flow even when it is inviscid. On the other hand, the 2-D inviscid flow calculation is expected to be an useful design tool. From the point of view, a new calculation method of the 2-D potential flow is developed. It can estimate the pressure on arbitrary point precisely, by using the spline function. The calculation result is compared to an analytic solution and shows a fairly good agreement. To examine the availability of the 2-D calculation to the 3-D inlet flow, the pressure measurement is carried out by an inlet model in the wind tunnel. The differences between the measured and calculated pressures are discussed.
