There are many areas in the ocean where two marine currents meet. An example is where the Gulf Streammeets with the Labrador current. These areas use to be well located and the currents have relatively lowvariations in speed. It is well known the eddies generation, cum solem and contra solem, up to the characterof the gradient of pressure and the hemisphere (Talley et al., 2011).We present the results of two numerical simulations for the meet of two theoretical and constant currentsto see how the entropy of the resulting velocity field evolves. The currents are defined to be perpendicularand the Navier-Stokes equations are numerically solved. In any case, the numerical tools have been the opensource finite/volume elements solver for multiphysics problems FreeFem++ (Hecht et al., 2012). The resultscan be briefly summarized as the time evolution of entropy, increasing in time even with constant currentsmeeting.
