A Transient liquid slug Flow was analysed on the basis of the scooping model and by applying equations of integral balance of mass and momentum for an arbitrary geometrical volume closed by moving surfaces through which liquid Flowed in and out. The analytical results agreed well with the experimental results of the Flow characteristics and impact force of the transient liquid slug. The dynamic behavior of the impact force was discussed with reference to the analytical results of the dynamic behavior of the Flow.
