摘要
In this paper,a simple numerical model of offshore currents is presented. A calculation scheme based on the isometric,implicit difference method is used and the points at which various physical quantities are computed are distributed in a staggered form.The finite difference scheme designed here conserve total generalized energy and it is solved by splitting into three systems,namely,the adjustment,development and dissipation processes.The results of the numerical verification indicate that this scheme is computational stable,and the simulated results are encouraging.
