Stratified flows are frequently observed in environmental and oceanic applications, which often involve interaction of momentum and scalar flux. In this study, Particle Image Velocimetry and Planar Laser Induced Fluorescence are applied to simultaneously measure the velocity and density fields of a turbulent jet discharged horizontally into an environment with density difference, for studying the mixing and entrainment process in stratified flows. The data are analyzed to gain understanding of the physical mechanism of vertical mixing (mixing along gravity direction) and horizontal mixing (mixing along horizontal direction) introduced by the turbulent jet flows. The dataset also provides a test platform for mixing models used in stratified flow simulations.
