Effect of Shocks on mixing and Thrust in Over-expanded Nozzles

WebThis module deals with a plane shock normal to the flow direction. This case represents the simplest example of a shock, in that changes in flow properties occur only in the direction of flow; thus, it can be treated with the equations of one-dimensional gas dynamics.
