In this work numerical analysis is used to carry out a parametric study of two-phase flow water-gasoil in a compact cyclonic separator (CCS). The study is oriented to produce a set of range parameters that may be used as a guide to control and manage multiphase mixtures separation with application to the gas industry, especially gas turbines. The cylindrical geometry under study has an aspect ratio of R=2.5 (where R=height/diameter). The CCS has two exits: one on the top for light liquid flow and one tangentially located in the bottom for heavy liquid flow. A finite volume approach has been employed with body-fitted coordinates in a 3-D solution of the liquid-liquid cyclonic flow. The turbulence was resolved using a RNG model, while the interactions between each component of the flow were addressed using a slip mixture model. The mixture under study is immiscible, and limited to the composition between 0.3 and 0.7 for water and consequently, from 0.7 to 0.3 for gasoil. The results indicate that the separation is sensitive to exist pressures, viscisity of light component gasoil and bubble size of the gasoil.
