FANS AND PUMPS

MULTI-STAGE PUMP

This analysis was carried out as the final check for the return passage of a multi-stage compressor, before moving to the production stage. As many as five million mesh-elements would be required to assure an adequate accuracy for the calculation of a whole unit. Even in SC/Tetra, it is wise to utilize the symmetry and periodicity of such a model. An analysis of the same accuracy can be done with a single pitch of the blades, which is just 1/7th of the whole, using periodic boundary conditions. The total number of elements is reduced down to 0.7 million. Yet, the results can be visualized as a "full" model.

SIROCCO FAN

An analysis of a sirocco fan requires many hours of work for mesh generation and transient state calculation, as well as any other kind of axial fans. SC/Tetra offers the discontinuous mesh interface and moving boundary functions for such a model. The meshes for the static casing and the rotating blades are generated separately using the auto-mesh generator. Afterwards, the two meshes are combined with a "discontinuous mesh interface" defined on their boundary, and can be analyzed easily as a single model. Alternative possibility is to use the steady ALE function - only the rotating section of a fan is treated in a rotating frame in the steady-state calculation. SC/Tetra provides solutions for a wide variety of fan developers who have not been able to do a performance analysis due to time limitations.
