In this work has been proposed a numerical scheme with the aim of simulatethe coalescence process between water drops immersed in a continuous phase(n-heptane). This numerical scheme is based in the Finite Volume method and twodifferent values for the initial velocity of the drops were chosen. Dependingof the initial velocity of collision some scenarios emerge, such as: permanentcoalescence, formation of satellite drops etc. For some snap shots thestreamlines are calculated for the different process of permanent coalescence.These streamlines allow the understanding of the dynamics of the dropletsimmersed on the n-heptane phase. The model used for the surface tension ispresented and its effects on the dynamics of coalescence of the droplets areshowed, which after some time tends to the spherical form.
