Hydrodynamic analysis techniques for high-speed planing hulls

摘要

A planing hull is a marine vessel whose weight is mostly supported by hydrodynamic pressures at highspeed forward motion. Its high-speed character has made it popular and thus the interest for planing hulls for military, recreational and racing applications is progressively rising. The design and analysis procedure for high-speed planing hulls, due to their performance and speed requirements, is very important. Access to a fast, accurate technique for predicting the motion of these hulls plays a significant role in improvement in this field. Over the past several decades, numerous investigations have been done on hydrodynamic analysis of high-speed planing hulls. In this study, the existing techniques for analysis of these hulls are reviewed. Understanding the strengths and limitations of these techniques will help researchers and engineers select the most appropriate method for optimal design and analysis of a hull. To present a comprehensive study on the existing techniques, they are classified into two major categories: analytical-experimental and numerical techniques. The numerical techniques are further divided into methods for boundary value problems and domain-dependent problems. Each technique is applicable only for a limited range of cases.
