TURBOdesign CFD - Pre-Processor

 

 

The process of generating a test case in TURBOdesign CFD consists of 5 main steps:

1. Input the Blade geometry

The pre-processor has been designed to import geometry from TURBOdesign1 automatically. Other CAD file formats will be implemented in the code shortly.

 

2. Grid Generation

The pre-processor allows for almost automatic mesh generation. However, the user also has flexibility to control the extend of stationary regions outside blade rows, tip clearance amount as well as detailed control of the grid clustering if required.

 

3. Specification

The specification window allows the user to specify the main flow parameters such as viscosity and density and in the case of pumps vapour pressure.

 

4. Boundary Conditions

This window allows the user to specify the inlet and exit boundary conditions either in terms of uniform quantities or in terms of profile boundaries that are read from a file.

 

5. Convergence Window

This window sets the convergence parameters. In 90% of cases the default setting provides convergence.

 

6. Convergence Monitor

The convergence window allows for the monitoring of usual RMS and maximum residual parameters as well as inlet velocity and exit velocity and flow angles.
