【Abstract】 Based on the numerical simulation of flow field,the influence of each part of the hydrocyclone on separation was studied according to the principle and method of computational fluid dynamics ( CFD) .The changes of the internal and external swirl pressures of the hydrocyclone,the radial pressure gradient,and Froude centrifugal Number along the tube length were quantitatively described for the first time,and the influence of each part of the hydrocyclone tube on the separation performance and the energy consumption was analyzed,an optimum calculation of the structure and size of the inlet of the swirl tube was made.更多还原
