Effect of Nozzle Contour on Flow Separation in Overexpanded Rocket Nozzles
Journal of Fluid Science and Technology, 2007 In the present paper, parametric numerical analyses of the separated transonic flows in overexpanded rocket nozzles are conducted. Several types of nozzles are examined numerically to clarify the detailed mechanisms of the occurrence of restricted shock ...

Aerodynamic Design of a Laval Nozzle for Real Gas Using Hodograph Method
Aerospace, 2018 We propose an approach for the design of the subsonic part of plane and axisymmetric Laval nozzles for real gases. The proposed approach is based on the hodograph method and allows one to solve the inverse design problem directly.
