The attractiveness of liquid metal blankets depends strongly on the degree of which peak pressures and temperatures can be controlled. These, in turn, are determined by the MHD pressure drop and velocity field. Accurate methods of predicting the pressure drop, velocity and temperature profiles in liquid metal blankets are necessary for blanket design and for plarming and analysis of experiments...

One of the well-known schemes for direct numerical integration second-order initial-value problems is due to Falkner. This paper focuses on construction a family adapted block Falkner methods which are frequency dependent solution initial value with oscillatory solutions. The techniques collocation and interpolation adopted here derive new methods. study properties proposed reveals that they co...

Weconsider liquid-metal free-surface flows subject to a strongmagnetic field, including film, droplet and jet flows, as potential means to remove high heat fluxes of (5–15)·106 W/m or larger in fusion applications. These considerations are partially based on the earlier experimental studies of free-surface flows performed in the Tokomak-3 reactor in the city of Shatura, Russia. We also review r...

The influence of a stationary mass flow on driven resonant MHD waves is studied for incoming slow and fast magnetosonic waves with frequencies in the slow and the Alfvén continua. In addition to the classic resonant absorption already present in a static plasma, driven resonant waves can also undergo overreflection. Depending on the strength of the equilibrium flow a variety of resonant MHD wav...

The combined effects of mass transfer and rotation on unsteady magnetohydrodynamic (MHD) free convection flow in a porous medium past an infinite inclined plate with ramped wall temperature has been investigated. The effects of thermal diffusion and heat absorption are also observed. Exact solution using Laplace transforms technique has been obtained for the velocity, temperature and concentrat...

We propose the generally covariant action for the theory of a self-coupled complex scalar field and electromagnetism which by virtue of constraints is equivalent, in the regime of long wavelengths, to perfect magnetohydrodynamics (MHD). We recover from it the Euler equation with Lorentz force, and the thermodynamic relations for a prefect fluid. The equation of state of the latter is related to...

The Hall effect in the magnetohydrodynamic (MHD) channel flow of a plasma leads to the presence of transverse Lorentz forces. The non-uniform distribution of these body forces may cause secondary flows to develop; these can exert a significant influence on the plasma momentum, thermal and electrical behaviour. The effect is predicted to be large for envisioned large-scale MHD devices. An experi...

In this paper, we report on numerical simulations of incompressible MagnetoHydroDdynamic flows by a two dimensional finite difference scheme associated to an appropriate projection method performed to characterize velocity-pressure formulations along the specified MHD duct by solving the set of differential equations of magnetohydrodynamics. In the present calculation, a working electrolytic so...

In this work, the theoretical study of steady flow for lift and drainage of Power law MHD fluid on a vertical cylinder is presented. The governing nonlinear differential equation has been derived from the momentum equation. The resulting equation is then solved using Perturbation method. Series solutions have been obtained for velocity, flow rate and average velocity in both cases. The graphica...

Recent discoveries of the intriguing " jet-torus " structure in the Crab Neb-ula and other pulsar nebulae prompted calls for reexamining of their theory. The most radical proposals involve abolishing of the MHD approximation altogether and developing of purely electromagnetic models. However, the classical MHD models of the Crab Nebula were hampered by the assumption of spherical symmetry made ...
