Self-similar solution of the subsonic radiative heat equations using a binary equation of state

, 2016
Radiative subsonic heat waves, and their radiation driven shock waves, are important hydro-radiative phenomena. The high pressure, causes hot matter in the rear part of the heat wave to ablate backwards.

Is radial extracorporeal shock wave therapy combined with a specific rehabilitation program (rESWT + RP) more effective than sham-rESWT + RP for acute hamstring muscle complex injury type 3b in athletes? Study protocol for a prospective, randomized, double-blind, sham-controlled single centre trial

Journal of Orthopaedic Surgery and Research, 2019
Background Acute injuries of the hamstring muscle complex (HMC) type 3b (interfascicle/bundle-tear) are frequently observed in various sports disciplines both in elite and recreational sport.

Quasi-perpendicular fast magnetosonic shock with wave precursor in collisionless plasma

, 2018
A one-dimensional particle-in-cell (PIC) simulation tracks a fast magnetosonic shock over time scales comparable to an inverse ion gyrofrequency. The magnetic pressure is comparable to the thermal pressure upstream.

Measurements of the principal Hugoniots of dense gaseous deuterium−helium mixtures: Combined multi-channel optical pyrometry, velocity interferometry, and streak optical pyrometry measurements

AIP Advances, 2016
The accurate hydrodynamic description of an event or system that addresses the equations of state, phase transitions, dissociations, ionizations, and compressions, determines how materials respond to a wide range of physical environments.

Time-resolved imaging and spectroscopy diagnostic of aluminized RDX and pure RDX under nanosecond laser ablation

AIP Advances, 2019
Laser ablation is a promising method for studying the chemical reactions and energy release in explosives. In this paper, we have investigated the combustion process of pure RDX and aluminized RDX through time-resolved observation of self-emitting ...
