Basic Principles of Impeller Design. Impeller design uses fundamental fluid dynamics and energy transfer principles to function effectively. The primary function of an impeller is to convert mechanical energy from a motor into kinetic energy in the fluid. This process is governed by several fundamental principles and equations. Bernoulli's ...

processes is critical to successful design and scaleup [2]. Impeller geometries. There are four general classes of impellers used in stirred tanks operating in low to medium viscosity fluids in the turbulent regime (Re > 10. 4): 1. Axial flow. The primary flow generated by an axial-flow impeller is directed down toward the base of the vessel.
