Abstrakt

In the present study the geyser phenomenon in the vertical LNG pipe was simulated with the vertical water column in the cylindrical glass tube with a coil heater around it. Heat flux to the water column was controlled by the electric input power to the heater. Ultrasound was applied from the bottom of the gersering water column to control the geysering phenomenon. As a result, it is clarified that the generation frequency and heat transfer of the geysering water column can be controlled by ultrasound emission.
