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

How to determine a spiral volute casing (turbocharger, pump) cross sectional decrease in value? I am trying to design a volute casing. Problem is, I don't know how much its cross sectional area decreases over time. For instance starting cross sectional area (0 degrees) is 100 cm^2, what will it be when it reaches 45, 90 degrees and so on? Is there any way to calculate it? I am sure that knowing starting and finishing cross sectional areas size (btw I know them) and just connecting them isn't a correct way.

It is re-edited regularly. - I try to keep this META up to date. However, I don't always catch everything, so please post links to any threads you think should be here. I will add them to the existing ones in the first post and periodically clean all other post from this thread.
