RWM 0 Report post Posted July 12, 2021 The reason I asked the question is that what I see is all the research that is being carried out at the moment is on hull shapes with a smooth surface. I'm looking at placing a certain shape plates over a hull to reduce the resistance. By applying these plates could the principle used in calculating resistance today be applied to this concept.

Mr. Heinrich von Zadow 5 Report post Posted July 12, 2021 This might not be the perfect forum for this kind of question since CAESES is not a CFD tool, but rather a parametric CAD and optimization platform that allows you to connect any CFD (or other external) software. However, as far as I know, there is -- and has been for a long time -- extensive research carried out in the field of alternative surfaces both on micro and macro scale. Whether you would actually model these things (e.g. fish-like scales or certain roughness and patterns) or just treat them specifically in your CFD code via boundary conditions depends. Both ways are feasible and have their pro's and con's. Cheers, Heinrich Share this post Link to post Share on other sites
