Normal shock in nozzle

WebNormal Shock Relation Types Description; Mach numbers: Mach numbers, specified as a scalar or array of N real numbers greater than or equal to 1. If normal_shock_relations and gamma are arrays, they must be the same size. Use normal_shock_relations with the mtype value 'mach'.Because 'mach' is the default of mtype, mtype is optional when this … Web26 de out. de 2024 · When the exit pressure is small enough, a normal shock will occur in the divergent section of the nozzle. An isentropic supersonic flow exists between the throat and shock while downstream of the shock there is an isentropic subsonic flow. There is therefore an increase in entropy across the normal shock, as we would expect.
