Proposal for a Bachelor’s-/Master’s Thesis
Combined EFD and CFD Approach using the Form Factor for Full Scale Ship Powering Prognosis
The HSVA is looking for interested students to work on the topic "Combined EFD and CFD approach using the form factor for full scale ship powering prognosis" as part of a Bachelor's or Master's thesis.
Accurate ship powering prediction is based on experimental model tests and scaled to full scale values according to procedures of the ITTC. The form factors method for the scaling of the ships resistance to full scale values is described in the ITTC ’78 guideline. With experimental methods, the determination of the form factor is controversial among researchers and is therefore not generally applied at the towing tank facilities worldwide. The upcoming use of a combined EFD and CFD methods for ship powering prediction will use CFD tools for the form factor determination and classical towing tests for the full scale ship powering prognosis.
The task of this thesis is to determine form factors of different ship classes at different draughts and scales with CFD and to compare them with results from model scale measurements in the towing tank. A special focus is laid on the HSVA reference models and common CFD benchmark cases. The full scale evaluation will be carried out with the classical pure EFD approach in comparison with the combined EFD and CFD approach as well as with the CFD results calculated in full scale.
Improvement of the combined EFD and CFD approach is to apply a numerical friction line replacing the ITTC ’57 ship correlation line which describes the frictional resistance at large Reynolds Number flows as they occur for full scale ships.
Based on statistical evaluation, differences of the results of both methods should be analyzed and fields of uncertainties as well as scale effects on special flow phenomena like transom flow, bulbous bow flows and roughness effects should be identified.
Within the context of the thesis offered here, the following aspects are to be dealt with:
- Determination of form factors with CFD calculations for two HSVA reference models and chosen CFD benchmark cases at different draughts and scales according to HSVA CFD standard calculation methods
- Conduction and evaluation of the form factor determination in the towing tank with HSVA benchmark models
- Determination of a numerical friction line according to HSVA CFD standard calculation methods
- Full scale ship resistance extrapolations based on EFD and combined EFD and CFD methods
- Statistical and direct comparison of the extrapolated results with full scale CFD calculations
- Discussion on uncertainties and scale effects
- Additional tasks: Suggestions for improvements of the HSVA CFD standard calculation
