Abstract : Measurements of mean velocity, turbulence intensity and Reynolds shear stress were made using a two-dimensional LDV system for a vertical bubbling jet in a cylindrical water bath subject to centric gas injection. The Reynolds shear stress in bubbling jet was such higher than that in single-phase free jet and almost agreed with estimated values based on the boundary layer approximation and the Boussinesq approximation.
