| Outline of Final Research Achievements |
The flow of high temperature heavy liquid metal is closely related to the problem of thermal-fluid behavior and material erosion/corrosion. In order to realize the velocity profile measurement technique, development of the ultrasonic sensor unit was performed. The experimental/analysis research has been performed for the transmission behavior of material dependence, the wall effect for signal transmission, the signal intensity in target medium. The developed sensor unit was successfully applied to the actual Pb-Bi flow measurement with the contactless method. And the prospect to a long-term operation was provided by the contact method with 800 hours experiment.
