| Outline of Final Research Achievements |
To improve the heat transfer characteristics, the effect of magnetic force (magnetothermal force) is evaluated quantitatively. First, a pipe flow with heat exchange from the wall is considered. It is found that, the heat transfer is locally affected such as enhancement and suppression. The tendency is like a rib mounted in the pipe wall for heated case, and bump for cooled case. Next, vertical parallel heated plates is considered for fin heat exchanger. There are similar tendency found. Additionally, the effect becomes different when the magnetic field is presumed by a analytical equation of block magnet and that induced by electric wires.
