- Title
Some features of the wall shear stress in a vertical tube around a small taylor bubble in an upward flow.
- Authors
Timkin, L.; Gorelik, R.
- Abstract
The wall shear stress induced by a Taylor bubble in upward flow in vertical tube has been studied with eight electrodiffusion friction probes placed in one cross section of the tube uniformly over its perimeter. The mean shear stress averaged over the tube perimeter in liquid film between the small (3-4 tube diameters) gas bubble and the tube wall is positive in the transient and turbulent-flow regimes.
