Abstract This paper deals with a Cauchy problem of the full compressible Hall-magnetohydrodynamic flows. We establish the existence and uniqueness of global solution, provided that the initial energy is suitably small but the initial temperature allows large oscillations. In addition, the large time behavior of the global solution is obtained.

Liquid jet impingement on a moving plate, which is applicable to cooling of hot plates in a steel-making process, is investigated numerically by solving the conservation equations of mass, momentum and energy in the liquid and gas phases. The free-surface or liquid-gas interface is tracked by an improved level-set method incorporating a sharp-interface technique for accurate imposition of stress and heat flux conditions on the liquid-gas interface. The level-set approach is combined with a non-equilibrium k-ε turbulence model. The computations are made for multiple jets as well as a single jet to investigate their flow and cooling characteristics. Also, the effects of moving velocity of plate, jet velocity and nozzle pitch on the interfacial motion and the associated flow and temperature fields are quantified.

Alfven Velocity

Stationary magnetohydrodynamics flows in nozzle-type channels in the presence of a longitudinal magnetic field are divided into three significantly different classes: super-Alfven flows in which the longitudinal plasma velocity is higher than the Alfven velocity calculated by a longitudinal magnetic field, sub-Alfven flows – with the opposite inequality, and Alfven flows in which the longitudinal plasma velocity coincides with the Alfven velocity over the entire length of the channel and the plasma density has a constant value. In the present work, stationary Alfven and close to Alfven magnetohydrodynamic flows obtained by using a numerical modeling of their relaxation processes in coaxial channels in the presence of a longitudinal magnetic field are considered.
