摘要

由于干涉效应,双体船的阻力与单体船的双阻力不同。如果半船壳之间的距离足够近,那么每个半船壳产生的波场通常会产生明显的干扰,从而产生有利或不利的影响。本文对Delft 372双体船的干涉效应进行了数值研究。进行了验证和验证研究,证明了所提出的数值模型用于分析干扰效应的潜力。研究了弗劳德数和半体分离对双体船总阻力、纵倾角和下沉的影响。干涉系数是根据双体船的总阻力和单体船的总阻力的两倍来定义的。最后,利用计算流体力学分析了流场特性、波型和压力分布。

Numerical investigation of interference effects for the Delft 372 catamaran
Due to interference effects, the resistance of a catamaran is not the same as the double resistance of the monohull. If demihulls are close enough to each other, the wave fields generated by each demihull usually significantly interfere causing either advantageous or disadvantageous effects. In this paper, the numerical investigation of interference effects for the Delft 372 catamaran is performed. The verification and validation studies are performed demonstrating the potential of the proposed numerical model for the analysis of interference effects. The investigation of the effect of Froude number and demihull separation on the total resistance of a catamaran, trim angle, and sinkage is conducted. The interference effects are quantified through the interference factor, which is defined based on the total resistance of a catamaran and double the total resistance of the monohull. Finally, the flow field characteristics, wave patterns, and pressure distributions are analysed using Computational Fluid Dynamics.

期刊介绍: The Journal of Engineering for the Maritime Environment is concerned with the design, production and operation of engineering artefacts for the maritime environment. The journal straddles the traditional boundaries of naval architecture, marine engineering, offshore/ocean engineering, coastal engineering and port engineering.
