Air Lubrication on Ship Hull
Air Lubrication on Ships in ANSYS
Hello all,
I’m a 3rd year undergrad student in MechE. For my fluids class, I have a final project in which I have to explore “Fluid Machines to help reduce energy consumption”. One of the options is Fluidic Air Lubrication (FAL).
I have a little bit of background in CFD, as I’m the Aero lead for our uni’s solar car team. I’ve ran CFD on ANSYS Fluent for our CAD models multiple times, and I understand the general math behind it pretty decent.
For this project I was thinking to do a 2D simulation with a ship hull, one with FAL and one without. I could then measure the coefficient of drag in both. My question is, how would I go about actually implementing this “air bubble” under the ship hull in ANSYS? All the previous CFD work ive done has never involved any lubricants, so I’m a little bit lost.
Any help would be great! Thanks :)

Read through the multiphase & wall film sections of the documentation, and then tell us which model(s) you think you should use and why.

I would recommend to do what @Rob mentioned and to focus on 3D runs in order to avoid having uncertainties in dealing with inter-facial scales using 2D solver.
