Numerical Study of Diffusion of Interacting Particles in a Magnetic Fluid Layer
نویسندگان
چکیده
Magnetic fluids are stable colloidal suspensions of ferromagnetic nano-particles (of size 10-20 nm) in a nonmagnetic liquid carrier. An initially uniform particle distribution in the carrier becomes spatially inhomogeneous in nonuniform magnetic fields. Motion of particles in magnetic fluids under the action of magnetic fields is of particular interest for contemporary mathematical and numerical modelling in ferrohydrodynamics.

Simulation of particle diffusion and heat transfer in a two-phase turbulent boundary layer using the Eulerian-Eulerian approach
This work investigates the response of two-dimensional, turbulent boundary layer characteristics over a flat plate to the presence of suspended particulate matter. Both phases are assumed to be interacting continua. That is, the carrier fluid equations are considered to be coupled with the particle-phase equations. A finite-difference technique with non-uniform grid has been employed for the so...

The problem of two-phase MHD boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. The effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. The governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...
