The application of CFD codes in the design process, even if inverse design methods such as TURBOdesign-1 are employed, play an important role in highlighting loss mechanisms in presence of viscous effects. In addition they can be used to provide estimates of the overall design characteristic including efficiency and head variation with flow rates. By using appropriate correlation or modelling they can also provide information such as noise generation in fans or cavitation performance (e.g. NPSH) for pumps.

Ease of Problem Definition
The graphical user interface in TURBOcfd allows for rapid mesh generation, including the specification of rotating and stationary region of the mesh and tip clearance. Also it is easy to specify boundary conditions and set default convergence parameters. So in less than 5 minutes it is possible to import a geometry, mesh it, add boundary conditions and set it to run either for a single point or characteristic computation.
Robustness and Computational Speed
- An extensively validated robust flow solver that has been developed over a period of 15 years at Florance University.
- TURBOcfd can converge very quickly. Typical computational time for 350,000 node computation on a P4 3.0 GHz PC is of the order of 30 minutes.
Flow Summary Information
The code automatically produces a summary table which lists all the important flow parameters such as Head, Euler head, efficiency, flow rate, NSPH for pumps and broadband noise intensity for fans.
