Operational Savings Through CFD

Operational Savings Through CFD

Computational Fluid Dynamics: The analysis of hull forms and their hydrodynamic performance 

The application of the analytical technique known as computational fluid dynamics (CFD) to the following areas can result in significant operational savings with very little outlay: 

  • Efficient voyage planning can reduce operational costs and emissions
  • The identification of the most efficient operating speed and floating position for any given vessel can result in minimal hull resistance and fuel consumption
  • Real-world data can be collected and analysed on-board in full scale to compare against predictions derived from computer modelling and tank testing

Design applications of CFD 

  • Provides enhanced visualisation and prediction of the physical properties of water as it flows along a hull and over other surfaces below the water line
  • Allows the analysis and mitigation of complicated geometries that may result in turbulence and flow separation, thereby affecting the efficiency of a hull
  • Flow visualisation using CFD analysis plays an important role in both initial design and refits when it comes to propulsion and hydrodynamics.  It allows the rapid and cost-effective evaluation of different propulsion solutions, hull geometries, appendage alignment and loading conditions, all of which have a major impact on energy efficiency

Maintenance applications of CFD 

  • Anti-fouling coating manufacturers are constantly developing new techniques to reduce the frictional resistance of their products. However with reductions in service speeds and increased length of port stays fouling remains an important issue. CFD can be used to predict the effects of hull fouling over time in terms of increased resistance, for use in voyage optimisation and budgeting
