Abstract
Basic experiments on the turblent mixing of horizontally-injected high-density solution in vertically-upward water flow have been performed. Also, numerical calculations have been performed for experimental results by the finite volume method. The boudaries between complete and incomplete mixing have been clarified from the exeperiments. In complete mixing, the injected high-density solution is entrained completely into the vertically-upward water flow, while in incomplete mixing, the solution once falls fairly down in the upward water flow and thereafter is entrained into the water flow. The numerical calculations predict experimental results qualitatively; however, it is necessary to improve the numerical calculations particularly in order to predict the boudary water flow rate.
