Question

Which of these approaches is not used to find the solution of the fully viscous flowfield in hypersonic flow?

(a) Viscous shock-layer solutions

(b) Parabolized Navier-Stokes solution

(c) Full Navier-Stokes equation

(d) Boundary-layer solution

This question was posed to me in homework.

My query is from Hypersonics and Computational Fluid Dynamics topic in section Numerical Techniques for Nonlinear Supersonic Flow, Elements of Hypersonic Flow, Couette and Poiseuille Flow of Aerodynamics

Answer 1

Right option is (d) Boundary-layer solution

The best I can explain: In analyzing the hypersonic flow, it is assumed that the flow is viscous throughout. There are three main approaches taken which are-Viscous shock-layer solutions, parabolized Navier-Stokes solution and full Navier-Stokes equation. These three equations are much more accurate than the boundary-layer equations in order to solve the fully viscous shock layer present over the blunt body in a hypersonic flow.
