Pump Impeller Simulation Using Ansys Fluent Software

This tutorial focuses on simulating a centrifugal pump impeller using Ansys Fluent® fluid simulation software. It starts with a ready numerical mesh, provided within an Ansys Workbench archive. The mesh is passed to an Ansys Fluent Component System in Ansys Workbench™ simulation integration platform. The rotational motion of the impeller is modeled by using Frame Motion in a steady-state analysis. The problem size is reduced by modelling a single blade passage with periodic boundaries. Turbomachinery Best Practices for flow initialization, convergence monitoring and solver settings are applied.

Learning Outcomes:

Following completion of this workshop, you will be able to:

• Open an Ansys Workbench archive with a given numerical mesh and transfer the mesh to Ansys Fluent software.
• Model the rotational motion of the impeller cell zone using Frame Motion.
• Apply rotational periodicity and simulate only one impeller passage.
• Specify appropriate turbomachinery optimized solver settings and solution flow field initialization.
• Visualize results like pressure distribution on the impeller walls in Ansys Fluent software.

Prerequisites:

This tutorial is written with the assumption that you are familiar with:

• Ansys Fluent software. Some steps in the setup and solution procedure will not be shown explicitly.
• Ansys Workbench platform.
