抄録

In order to obtain a uniform and stable molten metal film, the shape control function induced by high frequency magnetic field is utilized.<BR>Firstly, the falling behaviour of liquid film shaped by a slit nozzle was observed in a water-model experiment by use of a high speed VTR. The falling liquid is classified into two regions. Namely, one is denoted as the film flow region appearing in the middle part of the falling liquid and the other as the channel flow region appearing in both sides of the film flow region. The width of the film flow region decreased continuously with increase in the falling distance. A mathematical model predicting the falling behaviour of the liquid film is developed on the basis of hydrodynamics and is verified by the water-model experiment.<BR>Then, the effect of magnetic field on the falling molten-metal film is studied by the mathematical model taking into account the magnetic pressure induced by magnetic field.
