Sponsored jointly by the University of Bath Centre for Power Transmission and Motion Control (PTMC) and ASME Fluid Power Systems Technology Division (FPST) this international symposium provides a forum for leading-edge activities in the field of fluid power and motion control.

Both symposia feature lectures, tutorials, case studies, discussion groups, and short courses, as well as exhibits of the latest services and full-sized equipment. The Pump & Turbomachinery Symposia continue to be the only meeting organized by users for users from around the world. Please, visit us at booth #1607 at the 29th International Pump Users Symposium Exhibition in Houston, Texas. For more information click here.

“PumpLinx has enabled our engineering team to accurately simulate performance of GenShock and its internal design features. It is delivering more accurate results for our hydraulic pump and valve modeling efforts than previous CFD packages we have utilized, saving us time and money. A couple data points: our latest generation GenShock demonstrated empirical performance within 1.7% of our un-calibrated predictions. The ability to accurately simulate design features enabled us to rapidly hone in on design enhancements, delivering a 3x improvement in system efficiency over the previous generation. ”

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.

Based on the evaluation, HMS had the following testimonial for PumpLinx,

“PumpLinx for me has surpassed all expectations: 3D model preparation – 2 hours maximum, 1 hour on average. No problems with mesh creation – always created and there are no errors in the calculations because of the quality of the grid. Calculation of the first characteristic point is no more than 10-30 minutes, which is 10-30 times faster than our main program. Accuracy of the calculation for the pressure and for the efficiency in the range of 1% to 3% max (in the operating range of feeds, and for one pump and throughout the feature). To sum up the total: a great program for the engineer;quick and easy; Overall evaluation of 9 out of 10 (with 10 being a perfect virtual [Score])”
