Over the past few decades there has been much progress in understanding mixing with the help of advances in computerized measurement and simulation techniques. The use of engineering simulation as an integrated part of computer-aided engineering (CAE) brings advanced virtual prototyping to the mixing application area to predict and understand flow-dependent processes. In many mixing applications, simulation is proving valuable in order to gain insight into how to increase product quality, enhance vessel performance, reduce waste and cost and improve time to market. Today, a wide range of applications including, scale up, solid suspension, heat transfer, reaction and fermentation are modeled using ANSYS fluid mixing technology. In addition, by using ANSYS multiphysics capabilities, many aspects of the structural mechanics of a mixer, including the shaft vibration, upset conditions, structural forces, the design of the gears and shafts and power reduction, can be better understood and optimized. ANSYS mixing simulation tools are used to help evaluate key mixing parameters, such as blending time, circulation and the power number in agitated mixing vessels for any configuration of impellers and mixing conditions, shaft orientations, and for any vessel geometry. Beyond stirred tanks, mixing remains an important component of many processes. ANSYS simulations can offer a detailed understanding of tee mixers, jet mixers, as well as the mixing of polymers or multiple streams. ANSYS is dedicated to helping engineers better understand mixing applications. This dedication has resulted in ANSYS developing mixing centric advancements such as a mixing specific intuitive graphical user interface that has a mixing and process engineering focus, a set of advanced models that account for particle dispersion, complex impeller rotation, the ability to resolve micro and misso-mixing scales, complex rheology and the non-Newtonian fluids for creeping or highly viscous flows. Today, process engineers all over the world are using engineering simulations tools from ANSYS to meet their varied mixing needs, such as:
