Modeling Convection Diffusion with Exponential Upwinding
《Applied Mathematics》2013年第8期80-88,共9页Humberto C. Godinez Valipuram S. Manoranjan 
This paper shows the usefulness of the exponential upwinding technique in convection diffusion computations. In particular, it is demonstrated that, even when convection is dominant, if exponential upwinding is employ...

Corrected Nonconservative Schemes
《Chinese Annals of Mathematics,Series B》2006年第5期539-548,共10页Olivier PIRONNEAU 
Derivatives of discontinuities being Dirac singularities, it is usually not possible to multiply them by discontinuous functions. However in the context of conservation laws we have shown in a recent paper that it can...
