A new technique for reconstructing the geometry of well-mixed regions (pseudocaverns for Newtonian fluids) in unbaffled vessels agitated with radial discharge impellers eccentrically placed has been developed for obtaining their three dimensional geometry. The mixer frame rotates at low speed allowing the video system to capture a sequence of pictures of the flow patterns by using the laser ind...

Flow in baffled stirred vessels involve interactions between flow around rotating impeller blades and stationary baffles. When more than one impeller is used, which is quite common in practice, the flow complexity is greatly increased, especially when there is an interaction between the multiple impellers. The extent of interaction depends on relative distances between the impellers and clearan...

Fluid dynamics simulations were applied for evaluating the suspension of particles in stirred vessels. The spatial distribution of particles throughout the vessel was characterized by a single parameter, here called the suspension quality (σ). Based on simulation results, a semi-empirical correlation was developed that correlated the suspension quality with the vessel geometry and solid and flu...
