Designing and analyzing turbomachinery requires powerful modeling capabilities for machines that can operate in a wide range of flow regimes and have significantly different designs. Pumps and turbines can be of axial or radial design. They can be single stage, multi-stage, include a volute or collector. They can operate at extremely high rotational speeds and operate with incompressible or compressible fluids, in subsonic or supersonic flow regimes. ANSYS CFX and ANSYS TurboSystem provide powerful tools for the modeling of all types of rotating machinery. In addition, these tools can interact with other ANSYS preprocessing software to minimize design and analysis time.

Rob Blumenthal has been with ANSYS since 2000, working as a Senior Technical Services Engineer. He provides technical support for ANSYS fluids products and turbo tools. Rob’s areas of expertise include turbomachinery design and analysis. Prior to working at ANSYS, Rob worked at Aerojet for 15 years specializing in design and analysis of turbomachinery for liquid rocket propulsion. Rob received his BSME from UC Davis, and his MSME from SDSU. Rob has also taken additional graduate-level course work in the area of Computational Fluid Dynamics from UC Davis.
Outside of the office, Rob enjoys spending time with his wife and son. He’s active in two volunteer organizations, El Dorado County Sherriff’s Search and Rescue and the El Dorado Nordic Ski Patrol. Rob is also a licensed EMT in the state of California.
