General mixing machine which has rotor with blades have some problems such as influence on mixing fluids by share force at blade tip and occurrence of cavitation at high speed range. In order to solve these problems, the mixing rotor without blades had been developed. This rotor has very simple shape, which has 3 thorough holes in the mixing rotor. In the present study, the numerical analysis and experiment were carried out to know the basic characteristics of mixing rotor with columnar shape. As the results, the basic characteristics such as flow fields in the mixing tank, outlet velocity of rotor, mixing time and power consumption were clarified.
