CFD codes for surface piercing propellers

[aziziyeng]

I need some information about CFD codes for surface piercing propellers. Can you help me?

Welcome aboard :)

And, yeouch! CFD of a surface-piercing prop.... just thinking about it makes my head spin.

I have no idea how to do such a complicated model; indeed, I suspect there are only a handful of people who do. Two-phase flow is enough of a pain as it is, without adding turbomachinery and a dynamically changing grid to the situation.

Now, if you're looking to specify a surface prop, as opposed to doing an actual CFD simulation of the flow patterns surrounding one, there are established benchmarks for doing that....

here is a paper on CFD simulation on surface piercing propellers
