摘要：

The paper presents the first experimental results concerning the wall shear stress in an upward monodispersed microbubble flow in vertical tube. A bubble generator using a microfluid focusing technique was designed to produce monodispersed submillimeter bubbles. The experimental results allow to think that there is an optimal size of the bubbles and the optimal gas fraction in the bubble sublayer that provide the maximal mass transfer coefficient beween the flow and the tube wall.
