Surface cooling based on the thermomagnetic convection: Numerical simulation and experiment

In this paper we present the results of our numerical and experimental investigation of thermomagnetic convection in a temperature sensitive ferrofluid under the influence of strong non-uniform magnetic field. The convection is studied in a rectangular cell with permanent magnets attached to the cell walls. When the cell is heated from below, the observed intensification of heat transfer is significantly higher than that in the case of simple thermogravitational convection. The predictions of the numerical simulations are compared with the experimental results with good correspondence.
