Effect of Hall currents on unsteady magnetohydrodynamic two-ionized fluid flow and heat transfer in a channel

Raju T. Linga, Rao V. Gowrisankara

International Journal of Applied Mechanics and Engineering

2021

Vol. 26, no. 2

84--106

An unsteady magnetohydrodynamic (MHD) heat transfer two-fluid flow of ionized gases through a horizontal channel between parallel non-conducting plates, by taking Hall currents into account is studied. The governing partial differential equations that describe the flow and heat transfer under the adopted conditions are solved for the velocity and temperature distributions by a regular perturbation technique. Profiles for the velocity and temperature distributions as well the rates of heat transfer coefficient are presented graphically, and a parametric study is performed. The results reveal that the combined effects of the Hartmann number, Hall parameter, and the ratios of viscosities, heights, electrical and thermal conductivities have a significant impact on an unsteady MHD heat transfer two-ionized fluid flow characteristics.

Implementation of a Monte Carlo method to a two-dimensional particle-in-cell solver using algebraic meshes

Vol. 57, No. 2

313-316

Particle-in-cell (PIC) technique is a widely used computational method in the simulation of low density collisionless plasma flows. In this study, a new two-dimensional (2-D) electrostatic particle-in-cell solver is developed that can be applied to non-rectangular configurations.
