    Abstract

    The characteristics of turbulence, interfacial fluctuation and entrainment caused by an oscillating grid have been investigated. The turbulent intensities, integral length scales and organized eddy scales have been described with the distance from the grid and the physical quantities of grid oscillation. The r. m. s. values, integral time scales and predominant periods of the interfacial fluctuation have been shown as functions of turbulent Richardson number. From flow visualizations and results mentioned above, we have found how the integral scale eddies and organized eddies play roles on entrainment and suggest the minus 5/3 power entrainment law.
