A Study on Liquid Lithium Flow in Rectangular Duck Perpendicular to a Intense Magnetic Field

A research on high speed liquid metal lithium flow through a non expanding rectangular duck under uniform intense magnetic field is presented. A equations set with Poisson equation and Helmholtz equation, which control the electrical field and flow field respectively, has been deduced by analysis and Phsolver, a program to solve the equations set, has also been finished. The current density distribution and flow field in the non expanding rectangular channel with intense magnetic field have been obtained from Phsolver by applying the wall function in the boundary wall. The velocity profile in the duck appears M shaped.
