Abstract: The motion of the film separating two fluid phases is studied when it begin to be attracted into a thin pipe. Finite element method, especially the similar element is used. The elements attaching to the film are changed step by step in the calculation. The computed entrancing length variation is consistent with experiments. The computation offers the whole detail of the now.
