| 摘 要： | 用激光多普勒测速法(LDV)测量了一种胀流型流体——107 胶溶液的狭缝流的速度剖面和近壁速度。在对 Poiseuille’s 流的公式作有关侧壁影响的修正后,将 LDV 的测量结果和总体参量测量结果结合,分析了该流动的增强的迹象和数量。表明用 LDV 详细研究流动增强现象是可行的。

| Abstract: | LDV is used to measure the velocity profiles and near wall velocities fora dilatant flow-gel 107 solution flow in a slit. After some modification in the Poiseuille flow formulas has been made for side-wall effect correction, the results of LDV measurements combined with bulk parameters are utilized to analyse the enhancement evidence and quantities of the flow, The feasibility of using LDV to investigate flow enhancement phenomenon in detail is demonstrated. |
