Propan

an open-source Boundary Element Method Code

History

PROPAN: Propeller Panel Code.

Started to be developed at IST in 1996.

Originally for potential flow calculations on marine propellers.

Developed then by J. Falcão de Campos and João Baltazar.

Current PROPAN development team:

  • Guilherme Vaz (previous developer of sister code PROCAL of CRS-Ships / MARIN.
    Now blueOASIS and ISMT/UDE)
  • Tiago Gomes (blueOASIS)
  • João Baltazar (IST)
  • J. Falcão de Campos (IST)

Current Features

  • Wings and rotors (open or inside a shroud/duct).
  • Conventional and quasi-orthogonal grids.
  • Steady and unsteady flow.
  • Empirical rigid wake model and Wake alignment model.
  • Wetted and cavitation flows.
  • Sheet partial cavitation (both face and back sides).
  • Super-cavitation (one side only).
  • Leading-edge flow separation models.
  • Inclusion of 2d viscous corrections.

Applied, verified and validated for:

  • Wings
  • Open Propellers
  • Ducted Propellers
  • Current Turbines

Examples

Elliptical Wing. Different Wake model possibilities.
