ABSTRACT

The surface wave generation due to incidence of the uniform flow on the two sources submerged in the finite depth fluid is studied. A 3D linear problem is solved by the method of multipole expansions. The exact solutions for the velocity potential and the free surface deflection are obtained in the integral form. The computations for the free surface deflection on the basis of the Simpson method are carried out. The dependence of the free surface shape on the Froude number and the distance between the sources is investigated.
