ANSYS Vista TF Features

Performing preliminary optimization of turbomachinery designs on the basis of throughflow analysis, ANSYS Vista TF software takes initial rotating machinery designs (for example, from meanline software codes) and uses an inviscid 2-D approach to predict their performance. The 2-D solution is based on circumferentially averaged equations of motion. Included in the inviscid solution are empirical data to account for effects such as frictional losses, boundary layer displacement and flow deviation from the blade. Real gas properties can also be taken into account for more accurate throughflow analysis predictions for machines with refrigerants and other fluids that can differ significantly from ideal behaviour under typical operating conditions. The throughflow code solves in a matter of seconds for multi-stage machines, allowing many initial designs to be screened and poor designs to be filtered out before proceeding to full 3-D viscous flow analysis with ANSYS CFD. The 3-D fluid dynamics solution then can be used for final design analysis and more accurate performance prediction, particularly at off-design conditions and by taking into account effects not included in the throughflow analysis, such as clearance flows.

ANSYS Workbench Integration ANSYS Workbench Integration

Integration into the ANSYS Workbench platform allows users to directly import turbomachinery designs for throughflow analysis with ANSYS Vista TF. Using the system-wide parameter management inherent to ANSYS Workbench, design variations can be updated with the click of a button, including automatically generated reports for viewing with ANSYS CFD-Post.

ANSYS Workbench provides a clear input panel for ANSYS Vista TF, and allows the throughflow results to be fed automatically to ANSYS CFD-Post for report generation.

Rapid Single and Multi-Stage Analysis Rapid Single and Multi-Stage Analysis

ANSYS Vista TF solves a simplified set of equations on a 2-D meridional surface, with empirical correlations for loss, incidence, etc., and therefore runs in a matter of seconds or minutes. This rapid turn-around time allows users to improve their basic design early in the development cycle, before performing detailed analysis with full 3-D CFD as the design is refined.

The predicted effect of changes can be seen on the spot for both single and multi-stage predictions.

Flexible Correlations Flexible Correlations

ANSYS Vista TF provides a selection of correlation templates for different machine types, from compressors and turbines to fans and pumps. Detailed documentation allows advanced users to easily adjust loss and deviation parameters to meet specific needs.
