摘要
在实验研究的基础上,用计算流体力学软件(CFD)对与喷注噪声密切相关的压力场与温度场进行数值计算,定量分析了在不同温度时所对应的压力场与喷注噪声的关系.
Based on experimental data,numerical simulation of pressure and temperature distributions is carried out which are the critical factors in noise generation due to water-vapor injection by means of CFD software.The correlation between pressure distribution at different temperatures and steam-jet noise is quantitatively analyzed,which provides a theoretical evidence for further study on the noise generation mechanism.
