文摘

The method of characteristics is used to draw the dual bell nozzle profile. The thermodynamic-parameters of flow are evaluated and studied. Numerical simulations of flow in the nozzle are carried out. The obtained results are compared to the computed results of the literature. Boundary layer correction of the nozzle profile is performed.
