摘　　要：通过水系统悬浮物清除系统所需射流器建立的三维紊动射流数学模型,对特殊结构形式的射流器进行流场结构和射流紊流动力学性能的研究,通过数学模型计算射流器的紊流流场分布,掌握流场的流体动力学机理,从而获得最接近射流器紊流流场实际状态的描述方法。Through establishing turbulent ejector’s 3D mathematical model for the ejector required by the suspended matter removal system,the flowfield structure and turbulent flow dynamics performance of the ejector with special structure were studied and the ejector’s turbulent flowfield distribution was calculated through the mathematical model,including mastering the fluid dynamics mechanism of the flow field to obtain the ejector’s description method closest to the actual state of the turbulent flowfield.
