摘要
通过热敏电阻式和压力晶体式两种实验方法对高质量含气率垂直下降气液两相流进行研究 ,分析了绕过梯形柱体所形成的绕流尾流流态 ,研究表明 ,在高质量含气率垂直下降气液两相流中 ,不易形成稳定的涡街 ,且热敏电阻式检测器不适用来测试高质量含气率垂直下降气液两相流中的涡街 .
Based on the two ways of thermal resistance and piezoelecteric crystal, the vertical downward two phase flow with high mass quality of gas was carefully researched; and fluidity of the circumfluent wake current, behind a trapezoid column was studied too. The research evinced that, a steady vortex street is difficult to form in the vertical downward high air rate two phase flow and the way of thermistor sensor is not suitable.
