The design of the impeller is crucial for reactors, compressors, and pumps. It hampers the mixing patterns in a reactor and can also minimize the dead zones. No of blades, orientation angles, and axial placement of the blade are some of the parameters which are modified to optimize the mixing in the chamber.
Maintaining homogeneity, and increasing velocity with a reduction in pressure is the prime job that an impeller does. Based on the application the design of the impeller, spacing between the blades, thickness, and material of construction changes. Modeling of such systems uses CFD as its core simulation tool.
