Numerical study of a rotational MHD flow containing polydisperse nonconducting inclusions in a cylindrical pipe

Average characteristics are determined for the first stage of MHD flow in a conducting liquid containing nonconducting inclusions in a channel having nonmetallic walls exposed to crossed electric and magnetic fields. For the second stage, a structural approach is used to evaluate particle paths, clumping, and effects on clumping. Using these criteria, the angular velocity of the stationary rotational motion can be approximated. Particle motion in this rotating flow was considered. Particle paths were determined with an M-4030 computer by solving a second-order differential system. The Runge-Kutta method was used. Raising the field frequency and selecting the optimum ratio for the bulk electromagnetic forces was found to increase the particle concentration and the coagulation rate at the center.
