The flow with movement of single slugs in an annular channel was studied. The shear stress on both walls of the annular channel was measured using the electrodiffusion method. The averaged wall shear stress distributions along the channel length during gas slug motion are presented for different regimes. A significant difference in the values of shear stress on the inner and outer walls of the channel is shown.

环形通道段塞运动过程中的壁面剪应力

研究了环形通道中单个段塞运动的流动。使用电扩散法测量环形通道两壁上的剪切应力。在气段塞运动期间沿通道长度的平均壁面剪应力分布被呈现为不同状态。显示了通道内壁和外壁上的剪切应力值的显着差异。
