Pressure drop and flow distribution in a mini-hydrocyclone group: UU-type parallel arrangement

► A theoretical model of UU-type parallel mini-hydrocyclone group for the first time. ► Analytical solutions of the pressure drop and flow distribution. ► Influence of split ratio on the flow performance. ► An experimental apparatus for validation of the theoretical model. ► Optimal method of parallel design of mini-hydrocyclone group.
