Investigations on the Relation of Numerical Stability of Fluid Dynamic Equations and Entropy Production of Dissipation(I) The Criterion of Non Negative Definite Property of Entropy Production of Dissipation
An entropy in broad sense is suggested.The entropy equation is then deduced from a given model equation of advective diffusive problems.And it is displayed that the model equation has the non negative definite property of entropy production of dissipati
