## Chapter 4: Turbomachinery Performance Maps

The Performance Map system is a convenient tool for creating performance maps for turbomachinery cases.

The system has a Performance Map cell that can be edited to access the Turbomachinery Performance Map dialog box. This dialog box has two tabs:

- The Operating Conditions tab, for defining speedlines

- The Performance Map tab, for viewing those speedlines on performance maps (after solution results have been generated).

As a prerequisite to using the Performance Map system, the Project Schematic must contain at least one turbomachinery-related system that is configured with input parameters for rotational speed and mass flow rate at the base duty operating point.

The turbomachinery-related systems that are compatible with the Performance Map system are:

- Turbomachinery Fluid Flow

- Fluid Flow (CFX)

- Fluid Flow (Fluent)

- CFX

Note that the Turbo Setup system also has performance map capability. For details, see Operating Conditions and Performance Map. The capability described here is more generally applicable.

The following topics are discussed:

- Operating Conditions Tab
- Performance Map Tab
- Limitations
