Effect of Magnetic Field on the Dispersion of a Solute in Fluid Flow through a Conduit with Interphase Mass Transfer

摘要

In this paper, diffusion of solute in a Newtonian fluid flowing in a pipe/channel under the influence of transverse magnetic field with interphase mass transfer at the boundaries is analysed using the generalized dispersion model. The study describes the development of dispersive transport following the injection of a tracer in terms of the three effective transport coefficients viz. the absorption, the convection and the dispersion coefficients. The absorption coefficient does not depend on magnetic field but the convection and dispersion coefficients are influenced by the magnetic field. The effect of magnetic field on the mean concentration has also been discussed
