Assessment of CFD Capability for Hypersonic Shock Wave Laminar Boundary Layer Interactions

open access: yesAerospace, 2017
The goal of this study is to assess CFD capability for the prediction of shock wave laminar boundary layer interactions at hypersonic velocities. More specifically, the flow field over a double-cone configuration is simulated using both perfect gas and ...

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.
