Saturated pool-boiling heat transfer of toluene-solvent magnetic fluid on a horizontal surface
- Tokyo Inst. of Technology (Japan). Research Lab. for Nuclear Reactors
Saturated pool-boiling heat transfer of a toluene-solvent magnetic fluid containing magnetite particles of 0--36.5 wt% was investigated on a horizontal surface in a vertical magnetic field at pressures of 0.021--0.061 MPa. In the absence of a magnetic field gradient, the heat transfer was enhanced significantly using a magnetic fluid with dilute magnetite particles, while it was reduced for the case of dense particles. As the magnetic field gradient was increased up to 3.9 [times] 10[sup 5] A/m[sup 2], the heat transfer of the dense magnetic fluid was enhanced significantly in the heat flux region, although it slowly began to show a reduced heat-transfer curve again at a certain transition heat flux. The transition heat flux increased as the magnetic field gradient became larger, the magnetic concentration, lower, and the pressure, higher.
