450 “Further Computer-Analysed Data of the Wageningen B-Screw Series”



“Further Computer-Analyzed Data of the Wageningen B-Screw Series”, by Marinus Oosterveld and Peter van Oossanen, Published in “International Shipbuilding Progress”, Vol. 22, No. 251, July 1975 (ID No. 450).

In this paper the open-water characteristics of the Wageningen B-series propellers are given in the form of polynomials for use in preliminary ship design studies. These polynomials were obtained with the aid of a multiple regression analysis of the original open-water test data of the 120 propeller models comprising the B-series. All test results were corrected for the effects of laminar flow by means of the “equivalent profile” method developed by Lerbs. Additional polynomials are given for the scale effect on thrust and torque between model and full scale as derived by the same method.
