For flow visualization, dye was introduced as tracer in one of the fluid layer. The concentration of the dye tracer across the highly irregular turbulent interface was measured in the experiment using a video imaging method. The laboratory data of the interface were compared with a Large Eddy Simulation (LES) of the turbulent flow, which was conducted using a numerical scheme known as the Lagrangian Block Method (LBM). The highly irregular turbulent interface was correctly reproduced in the LES by the LBM in close agreement with the laboratory observation., authors=null, authorsList=null, authorCompany=null,
