In this study, the rising velocity of Taylor bubbles in inclined tube was investigated. In the experiment, the air-water two-phase flow system equipped with the Taylor bubble injector, which can inject arbitrary size Taylor bubble with a certain distance, was used. The inclined angle was 30-90 degree, the tube inner diameter was 20mm, the dimensionless bubble diameter λ was 0.6-2.0 and liquid velocity was 0.011-0.053m/s. As the result, the influence of the tube inclination and bubble size on the correlation for the bubble velocity with the separation distance of two consecutive bubbles was presented. On the basis of these results, the characteristics of the Taylor bubble movements were explained. Moreover, the fundamental data of two consecutive bubbles, i.e. the maximum trailing bubble velocity, the location of maximum velocity, the effective range of velocity and the damping ratio of velocity were reported.
