Analytic calculations of MHD equilibria and of MHD stability boundaries in fusion plasmas
In this work, two separate aspects of ideal MHD theory are considered. In the first part, analytic solutions to the Grad-Shafranov equation (GSE) are presented, for two families of source functions: functions which are linear in the flux function T , and functions which are quadratic in T. The …

Diagnostic techniques for EHD and MHD interaction
… actuators based on the Magneto-Hydro-Dynamic (MHD) and Electro- Hydro-Dynamic (EHD) interactions are potentially able to suitably modify the fluid-dynamics characteristics around a flying body without utilizing moving parts. This could lead to the control of an aircraft with negligible response …

Helical magnetorotational instability in MHD Taylor-Couette flow
… flow is a demanding task and different MHD groups around the world try to achieve it. The main problem lies in the fact that laboratory liquid metals which are used in such experiments are characterized by small magnetic Prandtl number. Consequently rotation rates of the cylinders must …

Formation and stability of the solar tachocline in MHD simulations
The solar tachocline is a thin transition layer between the solar radiative zone rotating uniformly and the solar convection zone, which has a mainly latitudinal differential rotation profile. This layer has a thickness of less than $0.05R_{\sun}$ and is subject to extreme radial as well as …

Impact of MHD-E3 on power system equipment and loads.
… – the magnetohydrodynamic late-time or MHD-E3 pulse – is characterized by a strong yet minute-long electric field that is capable of inducing quasi-direct currents in long conductors such as electric transmission lines. These quasi-direct currents, on the order of 1000 amps within the …
