CAESES is used for the parametric design of axial fans and similar turbomachinery products, mostly in the context of simulation-driven shape optimization. In particular, CAESES is used if you need robust variable geometry models for automated studies. The comprehensive CAD modeling capabilities are geared towards simulation and give fan designers full flexibility (no black box, customization possibilities). More information about turbomachinery design software can be found here. I have also attached a few animations that were generated in CAESES. The design variables of the axial fan model were varied automatically using the integrated variation methods. Note that this is a rather simple model which is also shipped with the software. It can be used as a reference design to set up custom models. The hub and shroud modeling is demonstrated, as well as the 2D-3D mapping of the cylindrical sections and some Boolean Operations to cut the blade at the tip and merge it with the hub. The fillet size can also be controlled by a parameter. If needed, you could also automatically derive the periodic flow domain for automated meshing with grid generation tools or CFD packages.

Hi together, With CAESES, we also focus on the design and optimization of volute geometries. There is a volute section on the CAESES website. Students and PhD students can get a free academic edition of the pro version - the product page gives more information about this. Basically, the software allows you to create robust parametric volute designs for manual/automated design explorations and shape optimization with CFD. In most cases, the volutes in CAESES are tailor-made models, i.e. you can fully customize the geometry design: Arbitrary parametric cross-section definitions, e.g. based on your area (A) and center of area (=>R) specificationsUse of point data for creating a volute surfaceUser-defined A/R functions (bsplines, mathematical functions)Individual tongue modeling with additional parameters for more detailed design studies and fine-tuningAnalysis and control of inlet/outlet area distributions. Usually, our CAESES support team helps you in setting up customized models, either through the helpdesk or, for more complex models and a quick solution, by means of a customer project. See the attachments for some pictures and animations (e.g. the A/R function gets varied as well as the tongue shape). Cheers Joerg LAST UPDATE: FEBRUARY 2017
