Mechanical Solutions Inc. (MSI), headquartered in Whippany, New Jersey, specializes in fluid machinery design, fluid dynamic analysis, mechanical design and analysis. In the energy industry, MSI focuses on analysis, testing and troubleshooting of all kinds of rotating, reciprocating and turbomachinery, using sophisticated analysis and testing tools. These specialists are using Star-CCM, an industry-leading simulation package to tackle design challenges in water pumps.
Major design challenges of water pumps include the unsteadiness of the flow, cavitation and rotating machinery. Star-CCM offers features that can successfully tackle these difficult physics while offering a streamlined, robust numerical design process. Geometry generation, meshing, solving, post-processing and optimization can all be done in an efficient workflow.
Features like the unsteady flow solver, unsteady cavitation model, Rigid Body Motion (RBM) for rotating domains, automated unstructured meshing for complex geometry and parallel processing capability offer the ability to explore multiple water pump designs in an economical manner. The system allows designers to easily predict pump performance at design and off-design points and avoid damaging effects of cavitation and erosion.
