Saturated pool boiling heat transfer of hexane-solvent magnetic fluid containing magnetite particles was investigated on a horizontal surface in a vartical magnetic field and field gradient. The heat transfer characteristics observed are qualitatively the same as those of the previous result for the toluene-solvent magnetic fluid ; i.e., in the absence of a magnetic field, the heat transfer was enhanced for the fluid with particles added dilutely, while it is reduced for a dense fluid. With increasing magnetic field, heat transfer of the dense fluid is enhanced significantly, but it is reduced above a certain transition heat flux. However, the transition heat flux and the heat transfer at high superheat region is higher compared with those of the toluene-solvent magnetic fluid.
