摘要
舰船测风传感器安装位置的不同会对其测量精度产生一定程度的影响,因此确定测风传感器合理的安装位置具有重要意义。本文在对常见舰船测风传感器位置布设方案进行分析的基础上,基于CFD理论,选用标准k-ε湍流模型,通过Fluent软件,对不同工况下LHA-1两栖攻击舰周围的流场特点进行分析,确定测风传感器的安装位置。研究结果表明,舰船周围的流场受其船体结构影响很大,在船首右侧及岛式上层建筑物中心,测风传感器所受到的扰流干涉性较低,比较适宜安装测风传感器。此研究可为大型舰船测风方案的制定提供参考。
The difference in the installation position of the shipborne anemometry will have a certain degree of influence on its measurement accuracy,so it is of great significance to determine the reasonable installation position of the shipborne anemometry.Analysis common shipborne anemometry location layout schemes,based on CFD theory,select the standard k-εturbulence model,through Fluent software,analyze the flow field characteristics around the LHA-1 amphibious assault ship under different working conditions,and determine the installation position of shipborne anemometry.The research results show that the flow field around the ship is greatly affected by the hull structure.On the right side of the bow of the ship and the center of the island-style superstructure,the disturbance to the shipborne anemometry is low and is more suitable for installation.This research provides a reference for the formulation of wind measurement programs for large ships.
