Parametric modeling of a propulsive system

Parametric modeling and optimization of a marine propulsive system using STAR-CCM+, OPTIMATE+ and CAESES

The aim of the study is to generate a fully-parametric marine propeller and propulsion system geometry to optimize the efficiency of the propeller using STAR-CCM+ and Optimate+ by CD-adapco.

Optimizing a marine propulsive system is a difficult task mainly caused by the complexity of the propeller geometry and its parametrization.

In collaboration with Friendship Systems CAESES is utilized to parameterize a five blade marine propeller. A shaft bracket is drawn in STAR-CCM+ 3D-CAD modeller and the combination of the two is analysed and improved using Optimate+.

The goal of the optimization is to maximize the efficiency of the entire propulsive system and look at the effects on thrust and torque of the propeller.
