Abstract	Until the 1950s, engineers and scientists studied the phenomena of fluid dynamics through analytical or experimental methods, but because of the complexity of the Navier-Stokes equations, which shape these problems, or because of the high laboratory cost involved in certain experiments, usually a specific problem could not be evaluated correctly. With the advancement of computational technologies, it was possible to use numerical methods to solve problems of fluid flow, allowing the detailed analysis of these phenomena with great precision and in short periods. Thus, this work aims to develop a numerical code in the FORTRAN 90 language, capable of solving the Navier-Stokes equations for transient, incompressible, twodimensional and low Reynolds numbers fluid flow problems. For the discretization of the governing equations, the finite volume method was used, with a structured mesh and staggered grid. The pressure-velocity coupling problem and the non-linearity of the governing equations were treated using the SIMPLE algorithm. Three studies were carried out to test the code created, comparing the results obtained in the present work, and the ones from the literature, the accuracy of the algorithm and the numerical method used. Key-words: Finite volume method, Computational fluid dynamics, Navier-Stokes, FORTRAN.
