description abstractNumerical simulations are carried out to investigate the spreading of two-dimensional plane turbulent aerated and nonaerated jets in a tank filled with finite water depth. A multiphase model is applied to simulate the problem under investigation. The governing equations, their numerical scheme, and the boundary conditions are presented. Aerated and nonaerated turbulent jets are simulated for a range of the jet velocity and width at exit, the initial air content at exit, and the water depth in tank. The simulated results show that a self-similar Gaussian velocity distribution exists from the distance downstream being larger than five jet slot width for both the aerated and nonaerated jets. Good agreement between the simulated velocity profiles and available laboratory experiments is obtained. The simulated slope of the jet velocity decay along the jet center line is in good agreement with the experimental measurements. The effect of air content on pressure distribution and the maximum impinging hydrodynamic pressure at the tank bottom is discussed.
