TL;DR: The method utilizes a source density distribution on the surface of the body and solves for the distribution necessary to make the normal velocity zero on the boundary and the flow velocities at points both on and off the body surface are calculated.
Abstract: : A method is described for calculating, with the aid of an electronic computer, the incompressible potential flow about arbitrary, non-lifting, three- dimensional bodies. The method utilizes a source density distribution on the surface of the body and solves for the distribution necessary to make the normal velocity zero on the boundary. Plane quadrilateral surface elements are used to approximate the body surface, and the integral equation for the surface source density is replaced by a set of linear algebraic equations for the values of the source density on each of the quadrilateral elements. After this set of equations has been solved, which is accomplished by a Seidel iterative procedure, the flow velocities at points both on and off the body surface are calculated. This approach is completely general. Bodies are not required to be slender, analytically defined, or simply connected.
TL;DR: In this article, a numerical method for the study of sloshing in tanks with two-dimensional flow is presented, which satisfies the exact nonlinear free-surface conditions, and artificial damping is introduced.
Abstract: A numerical method for the study of sloshing in tanks with two-dimensional flow is presented. The solution satisfies the exact nonlinear free-surface conditions. To avoid difficulties with transients, artificial damping is introduced. Comparison with a linear analytical solution, derived in this publication, shows that the numerical method gives reasonable results. Comparison with an approximate nonlinear analytical method, derived earlier by the author, indicates that the artificial damping leads to difficulties in special cases.
