Multi-dimensional simulations of bow shocks of massive, high-velocity runaway stars by Ramalatswa, Katlego Jafta

“…This study serves as the foundation of future work in which we will i) investigate the potential of observing these HVR bow shocks by making multi-wavelength estimates using established radiative transfer codes (e.g., TORUS) and producing synthetic images at different wavelengths (e.g., ultraviolet, Hα, infrared and radio), ii) couple these hydrodynamic models to established stellar evolutionary codes (e.g., MESA), and iii) include the effect of magnetic field and stellar rotation.…”

A study of nucleon unstable states produced in direct nuclear reactions by Hartmann, Kurt Miklos

“…An expression is derived for the wave function of such an excited nucleus, using the continuum shell-model theory. The bound and resonant states of the shell-model Hamiltonian are treated on an equal footing. …”

The study of the influence of the lifter height on the charge motion, velocity profile and power draw of a laboratory tumbling mill using DEM simulations by Uys, Adri Mari

“…The agreement between PEPT and the model predictions was limited to regions closest to the mill shell and the analysis was restricted for conditions where the lifter height was significantly smaller than the particle diameter. …”
