  In this paper is described a numerical scheme that is used to simulate the
coalescence process between clusters of water drops immersed in a continuous
hydrocarbon phase (n-heptane). Two different values for the initial velocity of
the drops were chosen. Depending of the initial velocity of collision some
scenarios emerge, such as: permanent coalescence, formation of satellite drops
etc. For some snap shots the streamlines are calculated for the different
process of permanent coalescence. These streamlines allow the understanding of
the dynamics of the droplets immersed on the n-heptane phase.
