CESE Schemes with Numerical Dissipation

Abstract As depicted in Chap. 2 , the interface between two sub-CEs (CD Fig. 2.7 ), belongs to SE of ( j, n ). The flux F C needs be calculated through Taylor expansion at point ) toward inverse time direction. a result, scheme is reversible. This violates second law thermodynamics. Thus, non-dissipative core suffers from unphysical oscillations for practical applications.
