摘　　要：为探究水平管内气液两相流流型变化激励流动噪声特性,结合VOF(volume of fluid)多相流模型与Lighthill声类比理论开展数值计算研究。结果表明,随着气相和液相流速增加,气液两相流呈现弹状流–层状流–泡状流的演变规律,进而导致噪声呈现不同变化趋势。随着频率增加,弹状流噪声呈现先减小后增大的趋势,而层状流和泡状流噪声分别呈现逐渐减小和增大的趋势。此外,在不同工况下,泡状流诱导噪声最大,弹状流噪声次之,层状流噪声最小。研究成果对于气液两相流噪声控制技术研究具有重要指导作用。In this research,the noise distribution characteristics induced by the change in flow pattern of two-phase gasliquid flow in a horizontal tube were explored by combining Volume of Fluid(VOF)multiphase flow model and Lighthill acoustic analogy theory.The results showed that with the increase in velocities of gas and liquid phases,the two-phase gas-liquid flow presented the evolution characteristics of slug flow,stratified flow,and bubbly flow,and consequently,different distribution characteristics of noise were formed.With the increase in frequency,the noise induced by slug flow decreased first,and then increased,while the noise induced by stratified flow and bubbly flow showed the trend that decreased and increased gradually,respectively.Additionally,the noise induced by bubbly flow was the highest,follow by that induced by slug flow,and the noise induced by stratified flow was the lowest under various conditions.The research can provide a guideline for the noise control of two-phase gas-liquid flow.
