 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 
    methods for form factor determination

General Conditions

Requirements: 

  • Basic knowledge on the ship powering and scaling procedures according to ITTC
  • Basic knowledge on practical maritime CFD applications
  • Optional: Programming skills in PYTHON and LaTeX
  • Reliable, self-motivated working attitude
  • The  applicant  for  this  proposal  of  a  Bachelor's/Master's  thesis  is  encouraged  to 
    discuss this topic with an appropriate institute and to ensure approval for this topic by  a professor if it is suitable for a thesis.

Time Period:

  • Start: asap
  • Duration: approx. 6 months, flexible
