An Extended Boundary Integral Equation for Structures with Oscillatory Free Surface Pressure
نویسندگان
چکیده
The conventional boundary integral equation for the solutions of linear wave-body interactions is extended to include the radiation solutions due to oscillatory pressures applied on the free surface. Coupled with the constraints which determine the pressure, the extended integral equation is applicable to various problems where a part of the bodies contains the free surface with oscillatory pressures. As illustrative examples, the analyses of wave interactions with an air-cushion vehicle and an oscillating water column device are made. As an additional application, we consider moon-pool and gap resonances where the use of oscillatory pressures is an efficient way to introduce artificial damping to suppress excessive free surface elevation of the potential flow.

In this paper we reduce a free boundary problem from heat transfer to a weakly Singular Volterra integral equation of the first kind. Since the first kind integral equation is ill posed, and an appropriate method for such ill posed problems is based on wavelets, then we apply the Chebyshev wavelets to solve the integral equation. Numerical implementation of the method is illustrated by two ben...
