2D simulations of hydrofoil profiles

rodb

Hello to everyone,

I should perform 2D multi-fluid simulations of NACA profiles used for hydrofoils and study the variation of Cl and Cd at different dives (distance from the sea surface), is it possible to do it with Fine Marine or do you recommend Omnis?

thank you,

R

    Hello,

    sorry for my late reply, I ran some test simulations, saving the results more frequently, in this way, as you advised me, I evaluated the points where the pressure and speed (so also the turbulent viscosity) varied the most and I improved the mesh at those points. I read the reference you sent me and it helped me.

    I probably did something wrong also in the simulation setup, I changed the boundary conditions like this:

    - x max, y max, y min -> far field, with Vx equal to the speed of the fluid in the case of study.

    -x min-> prescribed pressure.

    And imposing an initial solution with Vx as initial velocity equal to the speed of the fuid in the case of study.

    It seems to work residuals are drastically reduced.

    best regards,

    R

    ok great! Thanks for the information. The setup seems correct.

    Best regards,
