The three-dimensional turbulence model and hybrid finite analytic method were used to predict the behavior of near field for multiport buoyant jets in rivers. The predicted temperature dilution and velocity prove good by comparison with available laboratory measurements. An empirical formula for temperature dilution and velocity in near field for this kind of flow was given. The effect of parameters on the dilution behavior of multiple jets were also discussed.展开更多

Conservation equations were solved by hybrid finite analytical techniques. The hydrodynamic model was verified with the analytical solutions for the tidal forcing in an open channel. The simulation results are in good agreement with the analytical solutions.展开更多
