  In this work has been proposed a numerical scheme with the aim of simulate
the coalescence process between water drops immersed in a continuous phase
(n-heptane). This numerical scheme is based in the Finite Volume method and 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. The model used for the surface tension is
presented and its effects on the dynamics of coalescence of the droplets are
showed, which after some time tends to the spherical form.
