Abstract
Nucleate pool boiling heat transfer of ferrofluid on a horizontal plate; has been explored numerically. Extra necessary equations have been used in this model to simulate mass transfer and effect of magnetic field that had not considered in previous researches using mixture model. Also effect of negative and positive gradient of magnetic field on the heat transfer rate and bubble shape has been investigated. Results are in good agreement with experimental data.
