Determination of Parameters of Gas Phase Moving in Liquid Metal-Gas Flow in Magnetic Field of Permanent Magnets by Ultrasonic Pulse Echo Method

The article presents measurements and calculations of selected gas phase parameters in a liquid metal-gas flow in a magnetic field. The gas phase were argon bubbles, while the liquid metal was the GaInSn eutectic. The flow velocities of the gas bubbles, their equivalent diameter, and drag coefficient values were calculated for different argon inlet nozzles. The boundaries between the rise of individual bubbles and the chain flow were also indicated. The ultrasonic pulse echo method was chosen as the measurement method.
