     parameters and operation parameters, among which the structural type plays a very important role. the separation principle of a typical hydrocyclone was introduced. focused on a gas–liquid separation, numerical simulation of the typical hydrocyclone was carried out. the gas phase fraction distribution was analysed. it is shown that the separation effect was not satisfactory. a revising idea was thus proposed and developed step by step, so a new inner-cone hydrocyclone (ich) was designed. the inner-cone structure was thought to provide a more stable flow field for phase separation. it functions like a gas carrier that is beneficial for radially separated gas congregating on and growing into larger gas bubbles. it also produces an upward pushing force to gas bubbles, so as to enhance the gas–liquid separation performance, although the ich has lower inner tangential velocities than the typical hydrocyclone. numerical simulation and experimental study verified the analysis. pressure drop of the ich is much lower than that of the typical hydrocyclone; and the ich has a wider scope for the change of liquid split ratio or inlet gas–liquid ratio. development of the ich would provide a new thought for the design of other separators.
