Discrete-Adjoint Free-Form Shape Optimisation for Choked Hyperloop Vehicle Aerodynamics: Verified Gradients and Numerical Robustness
Confined evacuated-tube aerodynamics can choke at subsonic vehicle Mach number when a high blockage ratio forces the displaced gas through a narrow annulus. We developed an in-house MATLAB axisymmetric finite-volume compressible-flow solver and a 30-variable discrete-adjoint free-form-deformation (FFD) framework for a...
