Experienced user of ansys fluent.
Was part of team which manufactures UAV for SAE aerodesign competition, So I have experience regarding the simulation results vs experimental results.
For your ROV, I am confident to take this project.
Since most ROV deals with multiphase flow ( Air and water) for eg, boat
Since your simulation is regarding underwater ROV so, single phase flow will take place ( water) for eg, submarine.
I hope it helped.
Contact me if you think that I am the right guy.
Thanks
