Maine type of close clearance agitators No. impeller-type equipment, an impeller, usually composed of blades mounted to a central hub and rotated by a drive shaft, pushes and moves the material to be mixed. It can be used for designing radial and mixed flow impellers for compressors, blowers and fans. Such a complex design code has The manual design of the pump takes lot of labour as well as time. CFD analysis enables to predict the performance of the pump and a comparative analysis is made for the entire control volume by varying meshing. Thus, the impeller forces the liquid into a rotary motion by impeller action. The first is selection of proper velocities and vane angles needed to obtain the desired performance with the best possible efficiency.
