CFturbois made to interactively design radial, mixed-flow and axial turbomachinery: pumps, ventilators, compressors, turbines. The software is easy to use and does enable quick generation and variation of impeller, stator and volute geometries. Several models can be displayed, compared and modified simultaneously. It contains numerous approximation functions that may be customized by the user in order to implement user specific knowledge into the CFturbo-based design process. In spite of the creation of semiautomatic proposals, fundamental experiences in turbomachinery design are helpful but not necessary. An experienced turbomachinery design engineer should be able to design new high-quality impellers and volutes more easily and quickly.
CFturbo FEAis a free-of-charge software for strength simulation of 3D geometry. It provides a compfortable GUI for open source software Calculix and allows the calculation of static stresses and deformations as well as modal analyses. With CFturbo FEA one can calculate the strength of pumps, blowers, fans, compressors and turbines.
