摘要：

为了研究管内交变流动在流道侧向的速度相位分布特性,采用数值模拟方法针对平板流道内可压缩交变流动进行计算与分析.通过比较流道截面不同位置的速度波以及同一周期内不同相位时刻的速度分布,考察交变流动速度相位沿流道侧向的变化特点及其对速度分布的影响.根据典型计算结果,对瓦伦西数Va和最大雷诺数Remax对速度相位沿流道侧向分布特性的影响进行定性分析.提出定量描述流道侧向速度相位变化规律的评价指标截面平均相位差（CAPD）,利用CAPD进一步定量分析Va和Remax对管内交变流动速度相位侧向分布特性的影响.结果表明,CAPD随Va增加而增大；相比于Remax,Va对流道侧向速度相位分布的影响更显著.
Abstract:

Numerical simulation method was used to model and analyze the compressible oscillatory flow inside parallel plate channel in order to study the transverse velocity phase profile characteristics. The variation of velocity phase and its influence on the velocity profiles at the channel cross-section were investigated by comparing the velocity oscillations at different positions of the channel crosssection, and also by comparing the velocity profiles at different phase angles in a period. A qualitative discussion focused on the impact of Valensi number Va and maximum Reynolds number Remax on the phase profile characteristics based on the typical simulation results. An index parameter, crosssectional average phase difference (CAPD), was proposed to quantitatively describe the phase profile characteristics. The impact of Va and Remax on the phase profile characteristics was further quantitatively analyzed with the aid of index parameter CAPD. The analysis indicates that CAPD increases with a rise in Va, which has more significant influence on the transverse velocity phase profiles than Remax.
