Abstract

The necessity to improve the hydrodynamic performance of marine vessels has confirmed the urgency of conducting further investigations on biomimetic tubercles. In this work, towing tank tests were conducted at a range of speeds on conveniently prepared flat plates coated with 3D printed humpback whales mimicked tubercles.The results showed that the artificial tubercles induced a drag reduction of up to 1.3% compared to the bare flat plate. Following the experimental campaign presented, some relevant considerations for ship owners and naval architects will be proposed.
