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…

Spatiotemporal dynamics of transonic shock-wave/turbulent-boundary-layer interactions in an overexpanded planar nozzle

Justin Kin Jun Hew, Emanuele Martelli, Mahdi Davoodianidalik +3

We perform a combined numerical and experimental study to investigate the transonic shock-wave/turbulent-boundary-layer interactions (STBLI) in a shock-induced separated subscale p…

Analytical and Numerical Studies of the Non-uniformity induced Type II Asymmetric Cap Shock Mach Reflection in Over-expanded Supersonic Jets

Justin Kin Jun Hew, Rod W. Boswell, Christoph Federrath +2

A combined analytical and numerical study is conducted to investigate the asymmetric cap-shock non-uniform Mach Reflection (csMR) phenomenon outside of an over-expanded supersonic…

Centreline shock reflection phenomena for Supersonic Internal Flows in the non-Rankine-Hugoniot zone: Overexpanded Supersonic Microjets

Justin Kin Jun Hew, Hideaki Ogawa, Rod W. Boswell

The viscous and rarefaction effects on centreline shock reflection occurring in an overexpanded axisymmetric microjet have been investigated numerically by means of a fully coupled…
