When gas is suddenly injected from a nozzle into a stationary liquid in a horizontal circular pipe, a thin liquid film is left on the wall after the passage of the interface flout. The residual liquid film thickness in the case of the progress of the interface front at constant velocity is studied. The liquid film thickness quickly decreases and approaches an asymptotic value immediately after the front passes measured point and it decreases slowly after that. For low or high front velocity, the asymptotic value is almost constant regardless of the front velocity. For middle front velocity, it increases with the front velocity and depends on the capillary number. The asymptotic thickness agrees well with modified Bretherton's equation derived by replacing the inner diameter of the pipe by a virtual diameter. The limit front velocity, to which the modified Bretherton's equation is applicable, depends on the Reynolds number, which the virtual diameter or the thickness of gas bubble is used as the characteristic length.
