Improving the design of modern turbomachinery requires highly accurate numerical simulations. Complex flow features govern the performance of hydraulic turbines. One of these complex phenomena is the vortex rope which occurs in part-load conditions. It develops in the draft tube and causes large pressure pulsations, leading to structural vibrations and power swings.

In this webinar, we introduce you to Fidelity Flow and its pressure-based solver (formerly known as Omnis Open-PBS), demonstrating its advantages for simulating hydro turbines. Fidelity Flow is an easy-to-use multiphysics solver that provides fast and accurate results, including for unsteady simulations.

We use the GAMM Turbine as a test case. First, we perform a steady simulation to analyze performance at the design point, then followed by an unsteady simulation at a part-load operating point. The local values of pressure are monitored by inserting probes in the domain, and the vortex rope is characterized. Finally, we analyze the flow field to fully identify the vortex rope structures.
