Study on Flow Field and Pressure Drop in an Oil Removal Hydrocyclone

采用各向异性kε模型,用有限差分法,以SIMPLE算法为基础对旋流器内流场进行了数值模拟,通过数值计算得到了液液水力旋流分离器溢流管直径对压力降的影响、压降与流量的关系。通过算例与实验校验,得出各向异性κε模型能够模拟旋流器内湍流流场。

The flow field in a hydricyclone has been studied by means of numenrical method with a anisotropicκ-εmodel on basis of the algorithm of simple.It is foubd that anisotropicκ-εmodel can predict the swirling turbulent flow in a hydrocyclone.
