As long as you can define a signed distance function, and the function governing the motion of the propeller, WaterLily can simulate it!

- elil17 3y agoI don’t think that’s true. What about cavitation?
- b-fg 3y agoCavitation has nothing special other than multi-phase flow. And implementing a VOF method is definitely in our roadmap. You can currently simulate it without cavitation to get a feeling of the unsteady flow solution, or wait for us to implement VOF.
- samstave 3y agoCavitation is precisely what I would like to test... Also, will 'waterlilly' work with a viscosity to Air? Meaning - toroidal props are a newer entering thing in drones... and I'd like to find out if the above applies equally to fluid/air?
- b-fg 3y agoThen you should is a different solver that fills your needs. WaterLily is an incompressible flow solver that works in non-dimensional units (assuming constant unit density). So you can change the viscosity of the fluid by modifying the Reynolds number (with set a set characteristic velocity and length scale).
- JonChesterfield 3y agoWhat turbulence models do you have implemented? It's been ~ a decade since I played with CFD, wondering if DNS is computationally tractable these days.
