Qualifizierung einer Messtechnik zur Erfassung freier Grenzflächen bei Flüssigmetallen

The attempt to detect liquid metal surfaces is confronted with a number of difficulties. The main problems are the high reflectivity in vacuum at simultaneously high flow velocities and rapid surface motions. Currently no measurement methods for this problem providing unique results exist. In Order to develop such a method, a projection method has been modified by adding a second (transparent) screen. The development is completed by measurement of the circular hydraulic jump phenomena (GaInSn).
