Flow Analysis of 2 Suction Diffusers and a Suction Diffuser Flex Using Computational Fluid Dynamics (CFD)

Two Computational Fluid Dynamics simulations are contained herein. Both analyze leading products used to condition and improve flow entering a pump. The first Computational Fluid Dynamics analysis is of two popular styles of suction diffusers: the traditional cylindrical screen diffuser and the more recent model with a conical diffuser screen.

The second Computational Fluid Dynamics simulation is of the Suction Diffuser Flex. A fixed vane device placed in front of the pump’s suction side elbow which imparts a half revolution to the media flowing through the elbow (see back cover). This minimal deflection of flow negates the turbulence caused by the geometry of the 90 degree elbow and produces
