Abstract

Computational fluid dynamics (CFD), to which research efforts have been focused in the recent past is one of the most effective techniques of analysis of any fluid flow problems. Considerable part of towing tank tests for analysis of propeller characteristics are now being replaced by the CFD simulation on the computers. Here a four bladed Wageningen B screw series propeller has been designed for a specific vessel condition and numerically modelled and analysed using unstructured mesh in the flow domain. Validation of the numerical modelling of open water charectricts of screw propeller was achieved by comparing the results from the numerical analysis with the regression analysis based experimental series data.
