The direct observation of flow in the internal mixer with various rotor geometries is described. With decreasing distance between two rotors, additional transfer flow was observed in the inter‐rotor area. The FAN (Flow Analysis Network) method with assumption of fully filled, Newtonian fluid and isothermal condition was employed to simulate the flow patterns in the mixer with non‐intermeshing and intermeshing rotors. The distributive mixing capability was considered in terms of the fractional flow in the mixer calculated for various rotor geometries.
