CFD analysis service, any recommendations?

If this is not appropriate to post here please inform me to delete the thread.

Hi,

I want to take a VAWT design further and get some CFD analysis done on a design. Does anyone know or recommend a company/person that can provide CFD analysis as a service?

I know I could attempt this myself with ANsys etc but I am not confident that my meshing and simulation parameters will actually provide meaningful results.

Thanks.

Hi,

what would be the goal of such an analysis? Generating meaningful result of VAWT performance with FVM CFD is highly challenging and requires a lot of computational power and expertise – so outsourcing this could be very expensive in my view.

In general I would say that its quite possible to obtain very accurate predictions with QBlade if the VAWT design is purely lift driven (vs. a partially drag driven Savonious design which requires CFD analysis).

QBlade is great for the purely lift driven analysis but I want to see if a certain strut design would improve the performance vs a basic strut design.

Ideally I want to just provide some VAWT .stp files were all dimensions are the same except the strut design, then I can compare between;
basic strut, my strut design1, my strut design2.

How expensive is it to run 3 sims with the same setup but only the .stp different?

Hi,

I can’t really give you a good answer to your question, you would need to contact someone who has the capabilities and track record to run a comprehensive CFD study of a VAWT. If conducted properly it would require a lot of computational ressources and probably multiple weeks of work from someone experienced to do such an analysis. If someone claims such an analysis can be done quickly and for cheap I would have strong doubts…

Best,

David
