magnetohydrodynamics

Field of science concerned with the behaviour of ionized gases or liquids in a magnetic field. Systems have been developed that use MHD to generate electrical power.

MHD-driven ships have been tested in Japan. In 1991 two cylindrical thrusters with electrodes and niobium–titanium superconducting coils, immersed in liquid helium, were placed under the passenger boat Yamato 1. The boat, 30 m/100 ft long, was designed to travel at 8 knots. An electric current passed through the electrodes accelerates water through the thrusters, like air through a jet engine, propelling the boat forward.

After setting out the physical background, they cover solutions to the incompressible Navier-Stokes equations, the rapidly rotating Navier-Stokes equations, and the stability of Ekman boundary layers and boundary layer effects in magneto-hydrodynamics and quasi-geostrophic equations.
Patent and Trademark Office and has more pending, through research partner Lawrence Livermore National Laboratory, for its magneto-hydrodynamics (MHD) process.
After three chapters introducing microfluidics, the governing equations for mass, momentum and energy, and some basic flow solutions, the following 14 chapters treat hydraulic resistance/compliance, diffusion/dispersion, time-dependent flow, capillarity, electro- and magneto-hydrodynamics, thermal transport, two-phase flow, complex flow patterns and acousto-fluidics, as well as the new fields of opto- and nano-fluidics.
