Outline of Final Research Achievements |
It is found that volume of vapor bubble under non-uniform magnetic field decrease with increase of magnetic field intensity by both ways of electromagnetic induction method and optical visualization using a near infrared ray. Numerical simulation revealed that surface tension and magnetic buoyancy are dominant for bubble detachment By applying non-uniform magnetic field to the heater surface, the heat transfer enhanced up to 13 % in fully developed nucleate boiling region. It is possible to actively control of boiling heat transfer by applying non-uniform magnetic field.
