The Gas Liquid Cylindrical Cyclone (GLCC) separator is an attractive compact separator alternative to the conventional vessel-type separator and widely used in the petroleum industry with potential field applications. To understand the hydrokinetic properties of the flow inside GLCC body is the most important tasks for improving the performance of GLCC separator. Almost Researchers have performed CFD simulations to study the flow properties in GLCC separators in the past. This work is facing the difficulty due to the complex flow and huge dimension of GLCC. Thus, this paper focuses on studying the hydrokinetic properties of GLCC flow when inlet configuration is changed. To do this work, the inlet configuration is setup with different inclined inlet angles and different number & cross section of inlet such as single and gradually reduced inlet nozzle, dual inclined inlets nozzle. The eleven CFD models with different inclined inlet angles for both single and dual inlet GLCCs were performed to predict hydrokinetic of turbulent & swirl flow. The simulated results were compared with practical experiments in types of axial and tangential velocities. The distribution of radial, axial and tangential velocity profiles and their maximum magnitudes with respect to the change of inlet angle were carefully considered in this study. The results showed that there is excellent agreement between FEM simulations and practical experiments which allows to improve the performance of GLCC separator in industrial applications.
Abstract
The Gas Liquid Cylindrical Cyclone (GLCC) separator is an attractive compact separator alternative to the conventional vessel-type separator and widely used in the petroleum industry with potential field applications.

Almost Researchers have performed CFD simulations to study the flow properties in GLCC separators in the past. This work is facing the difficulty due to the complex flow and huge dimension of GLCC. Thus, this paper focuses on studying the hydrokinetic properties of GLCC flow when inlet configuration is changed. To do this work, the inlet configuration is setup with different inclined inlet angles and different number & cross section of inlet such as single and gradually reduced inlet nozzle, dual inclined inlets nozzle.
