A swirl motion of a cylindrical bath appears under a certain condition when the bath is agitated by bottom gas injection. The swirl motion can be classified into two types. One is called the shallow-water wave type, and the other is called the deep-water wave type. The condition for the occurrence of a swirl motion of the deep-water wave type was experimentally investigated based on water model experiments. Empirical equations were proposed for predicting the condition as functions of the gas flow rate, vessel diameter, inner diameter of the nozzle, and the physical properties of fluids.
