Model study has been carried out on the effect of chicken bones on the basic characteristic of a swirl motion of a bath agitated by a liquid jet. A ball of elliptical in shape is used as a model for cut chicken bone. A predetermined number of elliptical balls are immersed in a water bath and then the bath is agitated by a water jet generated above a centered bottom nozzle. The water thus injected is circulated with a pump to keep the bath depth constant. The jet becomes to swirl in the bath as the water flow rate is raised above a critical value. The water existing near the bath surface also swirls in the same direction. The initial thickness of the ball layer is found to play an essential role on the basic characteristic of the swirl motion of the bath. Some empirical equations are proposed to describe them.
