Satisfactory performance of large capacity pumps used in water treatment and supply, wastewater collection and treatment, power plant cooling water systems, and industrial processes is highly dependent on the hydraulic character of the flow approaching the pump.  Design standards have been established by the Hydraulic Institute that specify wet well or suction piping geometry required to provide appropriate approach flow.  However, due to the complex three-dimensional nature of the flow field, application of the standards does not guarantee success.  The state-of-the-art methodology for design of these facilities is to use a three-dimensional physical hydraulic model of the facility as an analog test bed to interrogate and adjust the design.  This presentation will acquaint the audience with the approach flow field performance standards, hydraulic modeling theory and application, and measurement techniques used in these studies through PowerPoint slides of the applicable equations, schematic diagrams, and photos of actual hydraulic models generated in the ENSR laboratory that was toured earlier in the evening.  The emerging use of computational fluid dynamics models to perform these studies will also be presented.
