【Abstract】 This paper conducted a numerical simulation of a single-stage self-suction aerator which has only one nozzle by using the method of CFD.By changing the structure parameters which could influence the aerator’s oxygenation capacity,the paper obtained the internal flow field’s flow pattern situation of the aerator.The results reflected different structural parameters’ influence on the oxygenation capacity of the aerator.And the key structural parameters of a jet aerator which has better oxygenation capacity was obtained.更多还原
