Abstract:
An investigation was made of the wave height due to a submerged point source and a source line. The wave height consists of two parts the regular wave and the local disturbance. The method of evaluating the integral representing regular waves is different in two regions, that in the vicinity and that far behind the singularity. In the vicinity of the singularity, the numerical integration is performed by the method of Gauss quadrature. At the far place, the method of stationary phase is used. The behavior of the wave height near the critical line is discussed. For the local disturbance, the integral can be evaluated in the closed form immediately above the singularity. A scheme involving numerical computation by high speed machine is worked out for other points. As an example, the wave height due to a simple form of submarine with given dimensions is calculated in detail. The influence of the submarine sail is included.
