Abstract

Submarines are one of the most advanced marine vehicles navigating from the surface of the water to the depths of the seas and able to perform various operations. Submarines have no benefit in terms of speed relative to surface floats, but also the advantage of a (moving underwater) dive deep into the deep seas. Diving and hovering of a submarine are carried out with the help of water ballast tanks (WBTs). Considering the importance of WBTs in the dynamic and static stability of the submarine, in examining the emergency maneuver operations using WBTs, complete modeling of the compressed air blowing process in the main WBTs of a submarine should be made. Blowing and unloading submarine ballasts can potentially use as a complementary control system to improve submarine maneuverability. Submarine ballast tanks can use as a tool for emergency hovering operation. This critical issue has simulated in this article using StarCCM + software, among which the governing equations and essential parameters have been investigated. Also, a sensitivity analysis was done on the results.

摘要

潜艇是最先进的海上交通工具之一，从水面航行到海洋深处，能够执行各种作业。相对于水面漂浮物，潜艇在速度方面没有任何优势，但（在水下移动）潜入深海的优势也是如此。潜艇的潜水和悬停是在压载水舱 (WBT) 的帮助下进行的。考虑到WBT在潜艇动静稳定性中的重要性，在使用WBT检查应急机动操作时，应对潜艇主要WBT中的压缩空气吹扫过程进行完整的建模。吹扫和卸载潜艇压载物可以潜在地用作补充控制系统，以提高潜艇的机动性。潜艇压载舱可用作紧急悬停操作的工具。本文利用StarCCM+软件对这一关键问题进行了模拟，其中研究了控制方程和基本参数。此外，对结果进行了敏感性分析。
