A Study on the Hydrodynamic Characteristics of a Synthetic Jet Propelled Underwater Vehicle
In this article, the drag characteristics of an underwater vehicle propelled by a synthetic jet (SJ) is numerically studied. The underwater vehicle studied is REMUS Autonomous underwater vehicle (AUV). The cruising speed studied is up to 10 knots. The actuation parameters of the SJ actuator are the same under different cruising speeds. When the SJ actuator works, the drag of the vehicle changes periodically. The SJ-induced additional pressure drag increases with increasing cruising speed. The additional friction force is negligible. The thrust of the actuator decreases with increasing cruising speed. The thrust outputted by the SJ actuator when used for underwater vehicle propulsion is smaller than the thrust of an isolated actuator. The mathematical model of the additional drag, the model of the thrust, and the velocity distribution is given to assist the analysis in this article.

More about this publication?
- Original and timely technical papers addressing problems of shipyard techniques and production of merchant and naval ships appear in this quarterly publication. Since its inception, the Journal of Ship Production and Design (formerly the Journal of Ship Production) has been a forum for peer-reviewed, professionally edited papers from academic and industry sources. As such it has influenced the worldwide development of ship production engineering as a fully qualified professional discipline. The expanded scope seeks papers in additional areas, specifically ship design, including design for production, plus other marine technology topics, such as ship operations, shipping economics, and safety. Each issue contains a well-rounded selection of technical papers relevant to marine professionals.
