SubmarineFlow is an inviscid panel method code that calculates the flow of water around streamlined underwater objects, such as submarines. It is developed by Dr Tim Gourlay at Perth Hydro and used for our ship hydrodynamics consulting.
For submarines in unbounded water
In "unbounded" (open-water) mode, SubmarineFlow uses the Hess & Smith (1964) panel method to calculate flow speeds and hydrodynamic pressure, around and on the submarine hull.
For near-surface submarines
In "near-surface" mode, SubmarineFlow uses the Havelock-source panel method to calculate flow speeds, hydrodynamic pressures, lift force, trim moment, wave resistance and wake pattern.
For near-seabed submarines
In "near-seabed" mode, SubmarineFlow uses the method of images to calculate flow speeds, hydrodynamic pressures, seabed attraction force, and trim moment on the submarine.
SubmarineFlow can also be used to model double-body flow around ships in deep water, shallow water and shallow channels.
