Two Computational Fluid Dynamics simulations are contained in this 21-page whitepaper which analyzes leading products used to condition and improve flow entering a pump.
The first CFD 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 simulation is of the CRV 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. This minimal deflection of flow negates the turbulence caused by the geometry of the 90 degree elbow and produces measurably better flow conditions and lower pressure drops than a suction diffuser.
