| 摘 要： | 高压气吹除主压载水舱是潜艇舱室进水情况下最有效的应急挽回手段之一.由于高压气吹除时压载水舱中剧烈的气液混合流动,导致建立的理论模型有一定局限性.本文通过CFD中两相流VOF模型对高压气吹除压载水舱的动态过程进行仿真,分析吹除过程中压载水舱中气-液混合现象、压力变化情况及压载水舱排水速率等特点,以验证高压气吹除压载水舱的理论模型.

| Abstract: | The high pressure air blowing ballast tanks are the most effective means of emergency to restore under flooded submarine.As the process of blowing,there will bring the flow of exquisite gas-liquid mixture in the ballast compartment.This led to the theoretical models that have certain limitations.The paper simulates the dynamic process of high-pressure air blowing ballast tanks by VOF two-phase flow model to analyze gas-liquid mixture phenomena,pressure changes,the ballast tank drainage rate during the process of blowing ballast tank,which provides the basis to theoretical models for the establishment of the high pressure air blowing ballast tanks. |
