Abstract
The upwind schemes are well suited to inviscid transonic flow but not to viscous flow. It is the opposite for central schemes. This paper pr esents a new approach which combines the central scheme and the upwind scheme. Lieu's flux splitting is selected to define this new mixed AU SM(+) Lieu scheme. The results, obtained on supersonic viscous configu ration, are compared to other schemes' results and to semi-empirical r esults. These calculations show the benefit of the present approach.
