The traditional frequency modulated quartz under liquid phase crystal sensor can not distinguish between the two effects which result in the frequency shift under liquid phase: mass loading and liquid damping. 传统的调频式石英晶体传感器工作于液相中时,无法区分引起频率偏移的两种不同效应:质量负载和液体阻尼。
Liquid loading flow is a particular case of two phase upward flow. Holdup and pressure drop of liquid loading flow ( including slug flow, churn flow and blowout) were investigated in a vertical tube, using different fluids as liquid phase. 以不同粘度的流体为液相,在垂直管中研究了液体填塞流(包括弹状流、块状流和泛出流)的持液率和压力降。
