Nonlinear evolution of magneto-hydro-dynamic (MHD) oscillatory phenomenon driven by the interaction with energetic particles has been studied in CHS using twin heavy ion beam probes. The measurements have provided the fine observation of internal structure of plasma quantities, such as electric field, density and magnetic field distortion during a cycle of the MHD phenomenon. The finding of a n...

Abstract the metal component arc plasma at muzzle of railgun is simulated by magneto-hydro-dynamic(MHD) model, and flow field under interaction between armature jet during movement position modeled simulated. The sheath model considered in simulation near movement. According to calculation results MHD transient current curve through analyzed, based on results, electromagnetic armature-arc-rail ...

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...

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...

Background Due to the Magneto-Hydro-Dynamic (MHD) effect, blood flow within the MRI’s magnetic field (B0) produces a large voltage during the S-T cardiac segment [1]. The peak MHD voltage (VMHD) can be comparable, in higher-field MRIs, to the R-wave amplitude of the real Electrocardiogram (ECGreal), so that VMHD reduces ECG-gating reliability and prevents ischemia-monitoring during cardiac imag...

Background High fidelity 12-lead ECG is important for physiological monitoring during cardiovascular interventions. A dominant ECG R-wave is essential for synchronizing cardiac MRI. Obtaining the real ECG in MRI is challenging due to a superimposed Magneto-Hydro-Dynamic (MHD) voltage (VMHD) [1], & strong induced voltages from MRI switched gradients. Detecting acute ischemia by ST segment [2] is...
