ABSTRACT

In the scientific community, water entry impact study has been remained focus by various authors across the globe in past decades. This paper reviews different analytical, experimental and numerical techniques for water entry impact problem. In this article, water entry problems have been broadly categorised into two main groups i.e. water entry of wedges (focusing on hull slamming loads only) and water entry of projectiles (focusing on impact loads, trajectory calculations and cavity dynamics). The first part of the review commences with theoretical studies in the realm of water entry of wedges then overviews key accomplishments in experimental and numerical techniques. The later section discusses the theoretical, experimental and numerical work carried out on water impact of projectiles starting from background then reviews some major research studies from 2000 to most recent advances. In the end, review is summarised and some recommendations are presented for future work.

摘要

在科学界，进水影响研究在过去几十年中一直是全球不同作者关注的焦点。本文回顾了进水影响问题的不同分析、实验和数值技术。在本文中，进水问题大致分为两大类，即楔形进水（仅关注船体撞击载荷）和弹丸进水（关注冲击载荷、轨迹计算和空腔动力学）。评论的第一部分从楔入水领域的理论研究开始，然后概述了实验和数值技术方面的关键成就。后面的部分讨论理论，从背景开始就射弹对水的影响进行的实验和数值工作，然后回顾了从 2000 年到最新进展的一些主要研究。最后，总结了回顾，并对今后的工作提出了一些建议。
