To study the influence of discretization schemes on the simulation results,the Second Order Upwind scheme,the QUICK scheme and the MUSCL scheme were applied to the numerical simulation of swirling turbulent flow outside the horizontal drilling nozzle.

The discretization scheme given by Perona and Malik is the approximation of the Perona-Malik Model.

The outflow fields of a simplified fastback car were studied with numerical methods of different turbulence models and diflerent discretization schemes with the CFD code STARCD.

The results show that all sorts of spatial discretization schemes have a good discrimination of shock wave,however.

Influence of discrete schemes on accuracy of radiative heat transfer by the finite volume method;

From comprehensive viewpoints of computational mathematics,physics mechanism and computational experiences,the evaluation and review have been made on some valuable discrete schemes for practical engineering to draw valuable hints to light future CFD study.

Symmetry of discrete schemes for 2-D transport equation;

Firstly, the "symmetry" property of the two-dimensional discrete schemes and the prior estimates of the three-dimensional discrete solutions have been studied in theory.

Section two gives the notations , lemmas and discrete schemes of the system of parabolic equations.

This paper proposes an effective and well adaptive discretized scheme based on B method.
