Diffusion Mass and Heat Transfer in a Plane Axisymmetric Layer of a Magnetic Fluid

Processes of magnetophoresis and Brownian diffusion in a suspension of magnetic nanoparticles (magnetic fluid) in an inhomogeneous magnetic field have been considered on condition that these processes are limited by concentration phase transitions between thermodynamic states of an ensemble of particles. Regularities of these processes have been established with the example of a plane axisymmetric fluid layer. It has been shown that due to the dependence of the effective thermal conductivity of the suspension on the concentration of particles, these processes may exert a substantial influence on the heat transfer through it.
