Finite-Strength Sensitivity and Euler--UTSD Correspondence for Guderley--Mach Reflection
Justin Kin Jun Hew
Weak shock reflection at nearly glancing incidence is governed, after the transonic weak-shock scaling, by a self-similar unsteady transonic small-disturbance (UTSD) free-boundary…
Distinguished Scaling and UTSD Structure in Weak Shock Reflection at Nearly Glancing Incidence
Justin Kin Jun Hew
We study weak shock reflection from a rigid wall in the joint limit of weak shock strength and nearly glancing incidence. In the distinguished scaling $\Mach=1+λα^2$, the inner ref…
Conservation of magnetic-helicity fluctuations due to spatial decorrelation of fluxes in decaying MHD turbulence
Justin Kin Jun Hew, David N. Hosking, Christoph Federrath +2
Hosking & Schekochihin (2021, Phys. Rev. X 11, 041005) have proposed that statistically isotropic decaying MHD turbulence without net magnetic helicity conserves the mean square fl…
Computation of Magnetohydrodynamic Equilibria with Voigt Regularization
Yi-Min Huang, Justin Kin Jun Hew, Andrew Brown +1
This work presents the first numerical investigation of using Voigt regularization as a method for obtaining magnetohydrodynamic (MHD) equilibria without the assumption of nested m…
