Propulsion
State-of-the-art analysis tools for design and optimization of marine propulsion systems
Simulation of propulsion systems is an important category of the Marine Industry with applications ranging from 2/4-stroke engines to ICE to electric motors.
  • Simulation of propulsion flows is an important category of the Marine Industry with applications ranging from cavitation prediction on propellers to the design of open water propellers and azimuthal trusters.
  • RANS Simulation of Complex Marine Flow Problems by Force Technology
  • RANS Simulation of Complex Marine Flow Problems by Force Technology
  • Temperature field of the oil in an Azimuth Thruster. The one phase simulation of the heat transfer in the thruster was solved using STAR-CCM+'s coupled solver.
  • Isosurface of vortices from a marine propeller
  • Propeller caviation on a state-of-the-art patrol vessel built to comply with ABS standards for high speed crafts (Maritime Research)

Using cutting-edge solver technology, CD-adapco’s customers have been able to tackle some of the most demanding problems facing the marine industry, allowing engineers to predict how designs will react in operation before budget is committed to the construction of expensive prototypes.

Specific capabilities in STAR-CCM+® that make it well-suited for modeling marine propulsion systems are:

  • Fully automatic and conformal meshing
  • Advanced cavitation modeling
  • Validated physics
  • Flexible modeling techniques including RANS, URANS, RSM, DDES, LES
  • Moving mesh, Moving Reference Frame and Overset mesh
  • Comprehensive set of reacting flow models to properly simulate combustion

Applications include:

  • Steady-state simulation for a single propeller blade using periodic conditions (i.e. first step propeller optimization): this can be used in lieu of open-water propeller tests;
  • Prediction of propeller-ship-rudder interactions, using a rotating region attached to the propeller and either sliding or overset grids: this can be used in lieu of self-propulsion tests;
  • Prediction of propeller ventilation and cavitation effects on performance;
  • Prediction of water-jet flows and performance of propulsion-enhancing devices, etc.;
  • Simulation of propeller dynamic pitch.
