Entrainment behavior on a density interface of stratified fluids is very important for the piping design of various plants. In the previous study, it was found that the dimensionless entrainment velocity was inversely proportional to an overall Richardson number. This tendency was derived by the turbulent energy released from the energy-containing eddy was proportional to the energy consumption by the entrainment. In the present study, the tangential injection made the horizontal eddy above the density interface. The entrainment is done by the tornado formation by the horizontal eddy. The entrainment velocity by the horizontal eddy was compared with the model of the turbulent energy consumption by the entrainment. The effective entrainment behavior was obtained with the horizontal eddy.
