Liquid metal MHD (Magneto-Hydro-Dynamic) systems can be employed to produce electricity from a wide range of heat resources. In such a system, a low-boiling organic fluid and a high-temperature liquid metal fluid mix. The former evaporates, and carries the latter to flow through an MHD channel, where the electricity is generated. The mixing process and the gas-liquid flow characteristics will h...

In this paper we discuss an analytical study of hall current effects on unsteady magneto hydro dynamic flow of an incompressible electrically conducting couple stress fluid through a porous medium between parallel plates, taking into account pulsation of the pressure gradient effect and under the influence of a uniform inclined magnetic field of strength Ho inclined at an angle of inclination ...

Background An important requirement for successful cardiac MRI is accurate gating. However, obtaining proper Electrocardiogram (ECG) gating inside the MRI is a difficult problem, due to the Magneto-Hydro-Dynamic (MHD) effect, resulting in frequent intermittent gating. The MHD effect generates a voltage due to conductive blood flow perpendicular to B0, and distorts the real ECG. Intermittent gat...

Liquid metal loops are used for heat removal and for the study of certain magnetofluidic phenomenon like MHD (Magneto-Hydro Dynamic) effects. These loops operate at high temperatures and carry fluids that are invariably toxic in nature. To ensure the purity of fluid in a closed loop application, non-intrusive electromagnetic pumps are used. We have designed and analyzed a prototype electromagne...

Abstract In this work, the effects of externally applied axial pressure gradients and transverse magnetic fields on electrokinetic energy conversion (EKEC) efficiency streaming potential nanofluids through a microannulus are studied. The analytical solution for electro-magneto-hydro-dynamic (EMHD) flow is obtained under condition Debye-Hückel linearization. Especially, Green’s function method u...

Star formation is usually accompanied by outflow phenomena. There is strong evidence that these outflows and jets are launched from the protostellar disk by magneto-rotational processes. Here, we report on our three dimensional, adaptive mesh, magneto-hydrodynamic simulations of collapsing, rotating, magnetized Bonnor-Ebert-Spheres whose properties are taken directly from observations. In contr...
