The analysis of secondary flows for tube-launched rocket configurations

“…Once the geometry of the corresponding inviscid plume-boundary is established by an appropriate potential flow analysis, a viscous mixing component is superimposed on the boundary. Wake closure conditions are specified in the form of a modified concept of incomplete turning of the plume near the point of shear-layer reattachment 7 Theoretical flow-fields have been calculated for various nozzle/ Since the launching of rockets from straight tubes will generally impose geometric restrictions to blow-by, the present analysis can be simplified by the assumption that the mass flow-rates which will be rejected from or entrained into the viscous jet mixing region should be small. This, in turn, allows the adoption of a linear velocity profile in the mixing region 8.…”
