Abstract
The effect of the turbine installation position on two-phase flow of a single six-blade ruston turbine in stirred tank with different agitation speeds is numerically simulated by using the large eddy simulation combined with mixture model. The result shows that when stirring low-density mixture, with the increasing stirring axle speed, volume fraction of low-density granules near the paddle is higher, while that near the barrel is low. When the paddle is installed with close distance to the tank bottom, the upper low-density granules are transported to the tank bottom to form good stirring effect. With increasing of the paddle location, distribution of low-density granules is hardly found at the bottom of stirred tank.
