Summary

A centered finite-volume scheme using artificial viscosity is applied to hypersonic flow past a sphere. The windside of the flowfield is characterized by the strong bow shock, and the leeside by separation and vortical flow. In order to obtain the correct bow shock standoff distance, we have improved our scheme in terms of conservation and viscosity switches. A number of computed examples of hypersonic flows past a sphere demonstrate these improvements and illustrate the features of the leeside flowfield.
