“…where u i denotes the mean velocity; p is mean pressure; r and n are density and kinetic viscosity, respectively; u i u j denotes the Reynolds stress tensor. In previous studies, researchers have widely utilized the Reynolds stress model (RSM) and large eddy simulation (LES) based on the Reynolds-averaged Navier-Stokes (RANS) method for numerical simulation of cyclone separators [24,25]. The RSM accounts for the influence of rotation, vorticity, high streamline curvature, and rapid changes in strain rate and exhibits good predictive capability.…”

An improved design was proposed by incorporating helical fins onto the vortex finder, and the impact on the comprehensive performance of the oil‐gas cyclone separator was analyzed based on flow field characteristics. The results revealed that the integration of helical fins led to a slight enhancement in the overall separation efficiency and a significant reduction in pressure drop, thus contributing to the decrease of energy consumption in industrial processes. The orthogonal experimental design (OED) method was utilized for the discussion and optimization of five structural parameters related to the helical fins. This study provides new insights for the design of internal components of oil‐gas separators.

“…Axial separators with multi-stage separation are used here with water flow rates ranging from 3 to 7 m 3 /h and an oil input fraction below 10% [5][6][7]. Due to the fact that the process of the separation of light liquids from water is not simple, simulation models are developed in order to increase the separation efficiency and to select the right type of separator [8][9][10].…”

“…With a simple structure and low maintenance cost, cyclone separators are widely applied in industrial two-phase/multi-phase separations such as liquid-gas separation in the natural gas exploitation process [1,2] and solid-liquid separation in the fluidized bed coal combustion [3,4]. Multi-phase separation is achieved by the centrifugal force [5,6].…”

CFD Investigation on the Performance of Cyclone Separators with Divergent or Convergent Insertion Pipes

For multi-phase separation, developing high-performance cyclone separators is highly demanded. In this study, different divergent or convergent insertion pipes bFelow the vortex finder are employed to improve the separation performance. The impacts of insertion pipe geometrical configurations on the flow characteristics, pressure drop, and separation efficiency are systematically analyzed. The results reveal that the employed insertion pipe can significantly affect the static pressure distribution inside the cyclone. A longer insertion pipe length and larger tilt angle result in a wider central low-pressure area and smaller overall static pressure. The divergent insertion pipes increase pressure loss, while the convergent insertion pipes augment pressure loss. A larger insertion pipe length significantly impacts the axial velocity distribution. For divergent insertion pipes, the maximum central axial velocity increases with increasing tilt angles and then decreases. For small particles (dp ≤ 5 μm), a convergent insertion pipe exhibits a better separation performance. When the particle diameter dp ≥ 5 μm, divergent insertion pipes with larger angles and lengths can significantly decrease the pressure drop while guaranteeing satisfied collection efficiency. When L = 75 mm and θ = 60°, the pressure drop is reduced by 7.8%. This study may contribute to rationally designing high performance cyclone separators and also paves ways for improving the existing cyclone separators.
