Abstract

in this paper, the TVD method is applied to the numerical solution of the flow over axisymmetric steady hypersonic viscous flow using TLNS EQUATIONS over blunt cone. In the TVD schemes, the ARTIFICIAL VISCOSITY is implemented using entropy condition. For hypersonic flow, Yee entropy condition has better stability and convergence rate. This paper presents a new entropy condition for increasing the accuracy and convergence rate of the TVD scheme which does not have the difficulty associated with Yee entropy condition for viscous flow in the hypersonic regime. The numerical solution has been compared, with the Beam & Warming shock fitting approach which shows that this approach has better convergence rate and accuracy.
