Abstract
The stirred tank reactor is one of the most commonly used devices in industry for achieving mixing and reaction. We consider a combined experimental/computational approach for the simulation of flow inside a stirred tank. Two sets of experiments are performed to measure the velocity field in the neighborhood of the impeller. The first set of PIV measurements are on six different r-z planes phase locked at 0°, 10°, 20°, 30°, 40° and 50° to the blade location. The second set of PIV measurements is on a curved 8-2 plane whose radial location is just outside the impeller blade tip radius. Measurements indicate that the impeller induced flow is dominated by three flow components: a circumferential flow, a tangential jet and pairs of tip vortices. A simple theoretical model is developed for each flow component and their superposition is observed to provide a good description of the impeller induced flow. The theoretical model is used as a velocity boundary condition for numerical simulation. The impeller induced boundary condition is fully three-dimensional. an important aspect that significantly enriches the mathematical representation of the primary source of motion. The results of two-dimensional and three-dimensional simulations are compared with measurements in the interior of the tank.
