Abstract

The numerical results of mathematical modeling of a two-phase, axisymmetric swirling turbulent flow in the separation zone of a centrifugal separator are presented. Calculations were carried out for various turbulence models: Spalart–Allmaras rotation/curvature correction (SARC) and shear stress transport rotation/curvature correction (SST-RC) linear models, SSG/LRR-RSM-w2012 Reynolds stress nonlinear model, and the new two-fluid model. In the numerical solution the longitudinal-transverse implicit scheme is used where the pressure is coupled with flow velocity fields using the SIMPLEC procedure. The results from comparing numerical calculations against each other and against experimental data are presented.

离心分离器内两相流的数值模拟

摘要

给出了离心分离器分离区内两相轴对称涡旋湍流的数学模型的数值结果。对各种湍流模型进行了计算：Spalart–Allmaras旋转/曲率校正（SARC）和切应力传递旋转/曲率校正（SST-RC）线性模型，SSG / LRR-RSM-w2012雷诺应力非线性模型以及新的二流体模型。在数值解中，使用纵向-横向隐式方案，其中使用SIMPLEC程序将压力与流速场耦合。给出了将数值计算相互之间以及与实验数据进行比较的结果。
