Here is a recent article about turbine wheel optimization where the blades and the scallops can be optimized at the same time within a fully-automated process. Such a "complete" and variable model allows you to consider the aerodynamic performance (CFD) and the stress characteristics of each generated design. Comes with a set of nice animations.
Hey, attached is an example of a vertical axis wind turbine, modeled in CAESES. It is fully parametrized, so that an optimization with an external cfd tool can easily be executed. The shape can be varied from straight blades up to blades that are twisted around the vertical axis (helix). The helix shape helps to minimize the effects of uneven distributed forces along the axis and during the rotation. As a result the VAWT will oscilate less which makes it more robust. Further design parameters: pitchcambercamber positionchord lengthradiusmid radiusI created a simple cfd calculation with STARCCM+ to show some post processing functionalities. Have fun with the model cheers vertWind_forum1.fdb
Hey, I think nearly everbody has heard about or seen an Archimedes screw. For those of you how haven't heard about it you can find more details here: https://en.wikipedia...edes'_screw I've created a small model of an archimedes screw. The Archimedes screw is created with a genericcurve for the spiral, a couple of lines and two sorts of surfaces. The model gives you the ability to change the length, outerradius, period and innerradius of the spiral and furthermore the outerthickness of the outercontour. Feel free to play around with it and try your own screws or other amazing spiral objects. Regards Karsten ArchimedesScrew.fdb
