Study on dense two-phase turbulent flow of power law fluid with particles in the pump impeller

The character of power law governing equation is expounded. First,power law fluid single phase and liquid-solid dense two-phase flow are simulated so that their results agree well with the experiment data. Then numerical study on turbulent two-phase flow of power law fluid in the pump impeller is performed. The result shows that from inlet to outlet,velocity is decreased and tension increases with radius and that the tension on the tension side is bigger than that on the suction side. The pseudothermal temperature on the tension side is smaller than that on suction side and bigger near the wall than that of the interior side. Finally,by comparing the two-phase flow of power law-solid and liquid-solid,it is found that the kinetic energy and pseudothermal temperature have certain difference.
