Investigation of single bubbles and bubble chains in liquid metal under the influence of magnetic fields

Strumpf, E.; Roshchupkina, O.; Shevchenko, N.; Eckert, S.

In the present study the ascents of single bubbles and of bubble chains in a liquid metal are investigated. For this purpose a benchmark experiment is set up, a cuboid vessel of the dimensions 144 x 144 x 12 mm³, which is filled with eutectic alloy GaInSn. A transversal magnetic field up to 1.1 T is imposed to this vessel. Ultrasound Doppler Velocimetry (UDV) is used to map the flow in the continuous phase of bubble chain regimes as well as the ascent velocity of single bubbles. X-ray radioscopy is applied to obtain detailed information within the disperse phase of bubble chains, such as bubble diameter, shape, trajectory etc.
