Computational fluid dynamics (CFD) provides a computing platform to simulate fluid flow, heat and mass transfer, and chemical reaction. In mixing industries, CFD is widely used to predict flow patterns, blending time, power consumption, pumping capacity, solid suspension, complex mixing with heating systems, and scale-up designs, etc. Additionally, CFD is powerful tool to optimize mixing designs in a short time at a relatively low cost in comparison to experimental measurements.
