Project objectives – Problem(s) addressed
Computational Fluid Dynamics (CFD) codes accurately predict the viscous flow around ship hulls at model scale, as validated with model experiments. However, for best practical use the focus should shift to ships at full scale. A main problem in that regard is that full-scale viscous-flow measurements needed for validation are lacking.
Computational Fluid Dynamics (CFD) codes accurately predict the viscous flow around ship hulls at model scale, as validated with model experiments. However, for best practical use the focus should shift to ships at full scale. A main problem in that regard is that full-scale viscous-flow measurements needed for validation are lacking.
The principal technical objectives of EFFORT are:
- To develop and validate the capability to make detailed, accurate, efficient and reliable predictions of the flow around ship hulls with propellers at full size.
- Thereby, to provide accurate and fast design tools to fine-tune ship and propeller designs for optimal operation in reality; thus reducing required engine power, fuel consumption and emissions; and reducing damage, cost and discomfort caused by an inappropriate hull/propeller combination.
- Thus, to make the design process faster, more accurate, more competitive and involving less risk.
Description of Work – Project summary
The work will mainly consist of:
The work will mainly consist of:
- A joint CFD development phase, in which extensions of existing CFD codes will be made that are essential to predict the flow around ship hulls at full scale.
- A full-scale measurement campaign in which extensive flow measurements at sea on board of two vessels will be done using Laser-Doppler Velocimetry techniques. Corresponding model-scale measurements will be done using PIV and other techniques.
- Collecting the most complete possible set of full-scale flow data for ships, consisting of some earlier experiments and the new data, in a database for full-scale CFD validation
- Extensive validation studies of full-scale CFD predictions to establish the level of accuracy and improve the modelling.
- Application of the tools developed and validated in the project to design studies proposed by the industrial participants in the project, to determine and demonstrate the benefits.
Expected results
The main output will be:
The main output will be:
- Extended and validated CFD techniques for predicting viscous ship flow at full scale, ready for practical application in design
- An introduction to, and evaluation by, industrial participants, of the validated CFD tools
- A database of full-scale ship flow experimental data for future use
- Areport of the design consequences of using the full scale CFD, detailed validations, and conclusions regarding the proper modellingand numerical approach.
This is expected to be a decisive step forward in the use and usefulness of viscous flow computations in European ship design; and thereby, in the quality and efficiency of the design process.
