Aerodynamic Design of a Laval Nozzle for Real Gas Using Hodograph Method

open access: yesAerospace, 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.
