Nucleate nanoferrofluid boiling on small heating surface in magnetic field

Abstract

Quite recently, considerable attention has been paid to boiling processes of nanoferrofluids in the magnetic field, in particular the influence of the magnetic field on boiling modes. The paper presents the experimental study of the stationary magnetic field effect on the nanoferrofluid boiling on a small heating surface, where only the nucleate boiling occurs. It is shown that at the low and medium field intensity, the heat-transfer coefficient increases, but further increase in the field intensity reduces this parameter. The hysteresis was found on the boiling curve under the influence of the external magnetic field.
