Abstract: “PumpLinx: Virtual Testing of Fluid Pumps, Motors, Compressors, Valves and Systems”

Computer simulations of pumps and compressors can now serve the same function as hardware testing. These simulations can be done in less time with less cost while providing engineering data of similar quality as experiments. Furthermore, computer modeling can be performed directly by the engineer doing the hardware design, thus providing a tight link between analysis and design optimization. Virtual testing can also be used to analyze problems with existing hardware, either as standalone components or in the context of a system. This presentation focuses on PumpLinx, a Computational Fluid Dynamics (CFD) tool that serves as a virtual test bed. PumpLinx predicts the performance of pumps and compressors in terms of head rise, power, efficiency, cavitation effects, noise, and/or damage. PumpLinx starts with existing designs created in a third party CAD package. Once the geometry is imported, the pump is meshed, modeled, simulated and analyzed, all in a single interface. Various operating conditions and fluid properties can be input to simulate the pump or compressor over a range of operating conditions. The output is similar to what would be measured for a fully instrumented test, with additional flow visualization and integrated quantities. This presentation will provide selected examples of the simulation of compressors and pumps.
