Marine and Offshore

XFlow's ability to model multiphase gas-liquid systems with free surfaces easily, quickly, and accurately makes it an ideal solution for a variety of marine applications.


Application Areas Include:

  • External Hydrodynamics
  • Internal Hydrodynamics (e.g., Sloshing)
  • Propellers and Other Moving Parts
  • Wave Action
  • Offshore Installations (e.g., Drilling Platforms)
  • And More.

External Hydrodynamics for Hull Design:  XFlow provides a virtual water channel module for free surface simulations. It can be used to analyze the flow around ship hulls, predict their resistance, seakeeping, loads on components, and the downstream wake of both surface and submerged watercraft.

Internal Hydrodynamics (e.g., Sloshing):  Dynamic loads across a tank structure as a result of the motion of free surface fluid confined inside the tank are an important safety issue. XFlow can be used to track the fluid motion, including splashing of single particles, and analyze the sloshing impact loads. It is possible to introduce any arbitrary prescribed movement e.g. from tabular data.  XFlow CFD's support for non-Newtonian fluids allows even very viscous fluids and slurries to be modeled.

Propellers and Other Moving Parts:  XFlow can be used to simulate moving parts with forced or constrained behavior, such as submarine propellers. It is possible to analyze the pressure and forces exerted by the flow on the blades, the fluid velocity distribution, the moment and propulsive force supplied by the propeller or the wake created downstream.

Wave Action:  XFlow CFD supports progressive waves boundary conditions by implementing linear and fifth order Stokes theory to simulate a wide range of sea conditions. A porous volume can be used to model the beach and study wave dissipation. XFlow is also able to simulate general 6-DOF motion (surge, sway, heave, pitch, roll and yaw) of any floating object, making it ideal for designing buoys, floating docks, or other seaborne structures.

Offshore Installations:  XFlow CFD can not only model free surface flows but do so for extremely large and compex structures, such as oil rigs or other seaborne structures.  The forces on the structure from normal and storm-level wave action can be simulated.
