Using Computational Fluid Dynamics (CFD), new insights can be obtained into the working principles of Energy Saving Devices (ESDs), which all serve to increase the fuel efficiency of a ship. The advantages of using ReFRESCO to study ESDs are explored in this article. The capability of simulating different moving objects, and their interaction in on calculation (applying the so-called Sliding Interfaces Technique) has increased the range of applications of the viscousflow CFD code ReFRESCO.

Fuel saving and emission reduction are motivating factors in the drive to improve marine propulsor technology and in the renewed interest in special devices that improve propulsion. Together with the industry, MARIN is actively investigating their working principles and the critical design aspects, using modern design and analysis tools. Fuel efficiency and reduction of CO2 emissions are expected to have a strong influence on the design and operation of ships. With the arrival of the Energy Efficiency Design Index (EEDI) in 2013…
