Ferrofluid Heat Transfer in a Box

This problem is used as a model problem that allows investigation of effects of the magnetic field and fluid properties in a well-defined situation. The work was done by Chittin Tangthieng and Bruce A. Finlayson at the University of Washington under sponsorship of Energy International, Inc. and EPRI .
