I want to do a numerical study of ship propeller. I can make a random 3D propeller model using CAD softwares. But is there any recomended propeller models or detail information of any propeller geometry - blade shapes, angles, dimensions etc?
Please see this link:

Dear Debasish Roy
AS I know the propeller blades are designed according to the NACA profiles. every cross section pf the blade is a NACA profile. however, the size of the profiles are different.
Hi mate!
Useful geometric, physical and structural properties that could be used for numerical simulations are given for sample marine propellers in the following papers:

There are the older Wageningen-B series propellers (apparently Caeses has a site which generates the geometry, didn't test it: https://www.wageningen-b-series-propeller.com/), or Gawn series. Both for which openwater data (thrust torque efficiency as function of advance ratio) is available. More recent propellers are the Insean E779A propeller or the propeller of the DTMB 5415 propeller, The KVLCC and KVLCC2, or the KCS vessels (see http://www.simman2008.dk/ ). The JBC https://t2015.nmri.go.jp/, The Lloyds Register full scale workshop ( https://www.lr.org/en/insights/articles/findings-of-lrs-full-scale-numerical-modelling-workshop/ )
Travaillez avec les hélices Wageningen-B series propellers comme pour la réponse n°4. Il existent beaucoup de résultats pour Z=4 . Ces séries ont une géométrie idéale.
