LEADING ENGINEERING SIMULATION CONFERENCE
Accelerating pump design exploration for better performance, faster
Some research estimates that pumping systems account for nearly 20% of the world's electrical energy demand, and range from 20% to 25% of the energy usage in certain industrial plant operations.
Energy Efficiency directives from the European Commission have led to the creation of an “Energy Efficiency Index (EEI)” for pumps. And, after several years of cooperation with the Hydraulic Institute (HI), in 2016 the US Department of Energy (DOE) issued its first-ever energy efficiency standard for commercial and industrial pumps, including a new “Pump Energy Index (PEI)”.
Not surprisingly, to meet ever-stricter government regulations, pump manufacturers worldwide are focused on improving the energy efficiency of their pumps.
In this presentation, we will describe a new workflow for discovering more efficient pump designs faster involving the use of CFturbo for design, STAR-CCM+® for simulation, and HEEDS for process automation and design exploration.
In this study, 300 different centrifugal pump designs were evaluated, using 16 impeller blade design variables, during ~48 hours of wall time, yielding 33 “better designs” compared to the baseline design – including one for which Power Consumption was decreased 8% (over an already manually optimized design).
