DIRECT NUMERICAL SIMULATION OF SECONDARY CURRENTS AND VORTEX STRUCTURES IN AN OPEN CHANNEL FLOW

Direct Numerical Simulation of turbulent flow in an open channel was carried out. The Reynolds number for the simulations was Reτ=150 and the aspect ratio was 2. The coherent vortex structures were also examined using visualization techniques. The significant results were the identification of inner...
