Paper Title
Effect of Spatially Different Electric Conductivity on The MHD Flow in a U-Shaped Duct with a Tiited Magnetic Field

Abstract
In the current study, a three-dimensional liquid-metal magnetohydrodynamic flow in a U-shaped duct is numerically investigated with the commercial software CFX. The U-shaped duct is formed by an inflow-, connecting- and outflow-channel, and the electric conductivity of the inflow channel wall is higher than those of the rest part of the duct walls. The external magnetic field is applied parallel with the diagonal of the duct cross section. The interdependency between the current density, fluid velocity, electric potential and pressure distribution is also studied for describing the electromagnetic characteristics of the liquid-metal flow. The result shows that the pressure gradient is higher when the duct-wall electric conductivity is higher. Keywords - Liquid Metal, Magnetohydrodynamic, U-shaped duct, Numerical Simulation.
