### 36.5.2. Model Data

#### 36.5.2.1. Reference Pressure

This sets the absolute pressure level that all other relative pressure set in a simulation are measured relative to. For details, see Setting a Reference Pressure in the CFX-Solver Modeling Guide.

#### 36.5.2.2. Heat Transfer

This model selection depends upon the type of fluid you have chosen. For details, see Heat Transfer in the CFX-Solver Modeling Guide.

#### 36.5.2.3. Turbulence

The models available depend upon the fluid that has been chosen. For details, see Turbulence and Near-Wall Modeling in the CFX-Solver Modeling Guide.

#### 36.5.2.4. Mass Flow

- Per Component

  Specify the mass flow per modeled (mesh) sector.

- Per Machine

  Specify the total mass flow (that is, for the full wheel).

- Per Passage

  Specify the mass flow per blade set (including splitters).
