Abstract

This research paper investigated the hydrodynamic resistance of Multipurpose Amphibious Vehicles (MAV) due to navigate in low water depth numerically. This type of vehicle and other coastal floating vehicles encounter the problem of a small under keel clearance with river bed. The proper estimation of ship resistance and squat is influence largely on the power calculation in the design stage. The present work describes the effect of shallow water on the Multipurpose Amphibious Vehicles (MAV) resistance at different speed using Computational Fluid Dynamics (CFD) techniques. A comparison in the drag on the hull is illustrated between depth restriction and infinite depth water. This paper provides a wide introduction into the problems of modelling of the restricted water depth effects on the ship behaviour, specifically hydrodynamic resistance and squat using CFD which is applied by ANSYS-CFX14.0.

浅水对多用途水陆两栖车辆阻力影响的数值估计

本文对多用途两栖车辆（MAV）在低水深航行时的水动力阻力进行了数值研究。这种类型的车辆和其他沿海漂浮车辆遇到了龙骨下与河床间隙小的问题。船舶阻力和深蹲的正确估计在很大程度上影响着设计阶段的功率计算。本工作使用计算流体动力学（CFD）技术描述了浅水对不同速度下多用途两栖车辆（MAV）阻力的影响。比较了深度限制和无限深度水对船体的阻力。本文广泛介绍了利用ANSYS-CFX14.0应用的CFD模拟限制水深对船舶行为的影响，特别是水动力阻力和深蹲的问题。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
