Starting from the momentum equation, a projection angle equation of the planar flyer plate under detonation driving is derived in the moving reference frame by regarding the material as incompressible fluid and considering the force between the neighbouring segments.

And some analysis is made on the error emerging when low speed flow is calculated as incompressible fluid.

The flow of incompressible fluid entering into porous medium region from free space region in a circular pipe were analysed in the paper.

Based on the dynamic hybrid grid generator and the implicit unsteady incompressible flow solver developed by the authors in previous work,the schooling of three fishes in a triangular array is studied in this paper.

Based on the dynamic hybrid grid generator and the implicit unsteady incompressible flow solver developed by the authors in previous work,the schooling of four fishes in a \'Diamond\' array is studied in this paper.

Refined-element methods to solve elastic incompressible problems;

A modified upwind difference method for problem of contamination by incompressible nuclear waste;

Stabilized equal interpolatiou u-p FEM for incompressible plastic problems;

The application of fringe method as the outflow boundary condition for the direct numerical simulation of compressible flows;

The large eddy simulation is applied to simulate a 3-D square channel compressible flow around a wall-mounted rectangle cylinder.

For the numerical simulation of compressible flows, characteristic boundaryconditions are often being used to ensure that the disturbances can pass through theboundary without causing reflections.
