A two-dimensional shallow flow equation is used to describe the tidal currents, and a Eulerian-Lagrangian semi-implicit finite difference method which was introduced by V.

Improved locally one-dimensional finite difference scheme for three dimensional hyperbolic equations with nonhomogenerous boundary condition

In this paper,a finite difference method for initial-boundary value problem of Eckhaus equation is considered,and an energy conservative finite difference scheme with condition is proposed.

By means of the finite difference scheme of characteristic method, the transient flows are simulated for the attitude control propulsion subsystem during the pulse operation.

In calculating onedimensional cylindrical flow problems,famous Wilkins finite difference scheme under Cartesian coordinate system can get exact symmetry with peripheral grids zoned by equal angle,and get severe nonsymmetry with peripheral grids zoned by unequal angle.
