| Outline of Final Research Achievements |
First, on the subject A of development of seawater magnetohydrodynamics (MHD) power generator/hydrogen generator utilizing ocean/tidal currents, it was found that the effect of a rectifier on the velocity distribution inside the helical-type generator. In addition, the electromotive force obtained was in agreement with the calculated value in stable helical flow and was independent of the direction of the induced electric field. Second, on the subject B of development of liquid hydrogen (LH2) tank for marine transportation from the view point of sloshing, the temperature distribution and static level-detecting characteristics of an external-heating-type superconducting magnesium diboride (MgB2) level sensor for LH2 was studied. Then, the optimum heater input to long MgB2 level sensor was able to estimate. In addition, the MgB2 level sensor showed good dynamic level-detecting characteristics, so that 3D sloshing measurements were carried out with several level sensors.
