Investigation Methods on Hydrodynamic Performance of High-Speed Vessels With Interceptor

_ In most of the high-speed planing hulls, the hydrodynamic forces are greater than the hydrostatic forces. With an increase in speed, the rate of increase in drag is greater in such vessels. Studies have developed energy-saving devices, such as stern flaps, wedges, hull vanes, and trim tabs, to reduce drag and trim on high-speed crafts. The investigation and design method for high-speed vessels with stern appendages is important to understand their performance. The approach for predicting the motion of such hulls plays a crucial role. Several studies have been done over the past on hydrodynamic analysis of high-speed vessels mounted with stern devices. The focus of this paper is to review the existing investigations on hydrodynamic studies of high-speed vessels mounted with a stern interceptor. Comprehending the robustness and constraints of these approaches will help designers and researchers to select the best method for the effective design of the stern appendage and examine its performance. An extensive study is made and presented on existing experimental and numerical techniques. Mounting stern appendages for high-speed vessels and their hydrodynamic performance vary for each case.
