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...

in this paper, the stability of a functionally graded magneto-electro-elastic (fg-mee) micro-beam under actuation of electrostatic pressure is studied. for this purpose euler-bernoulli beam theory and constitutive relations for magneto-electro-elastic (mee) materials have been used. we have supposed that material properties vary exponentially along the thickness direction of the micro-beam. gov...

We continue our investigation of Lithium Lens (LL) for usage in ILC positron conversion system. Magneto-Hydrodynamic and Thermo-dynamic problems discussed in association with ~100 kA feeding pulsed current. Set of Partial Differential Equations used for description of magneto-hydrodynamics phenomena in liquid Lithium flow. Calculations confirm feasibility of liquid Lithium system. Some interest...

Unsteady slip-flow of second grade non-Newtonian electrically conducting fluid over an oscillating sheet has been considered and solved numerically. A second-order slip velocity model is used to predict the flow characteristic past the wall. With the assumption of infinite length in x-direction, velocity of the fluid can be assumed as a function of y and t, hence, with proper variable change pa...

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...
