Fac. Ing. VL - 25 IS - 42 SE - DO - 10.19053/01211129.4633 UR - https://revistas.uptc.edu.co/index.php/ingenieria/article/view/4633 SP - 99-110 AB - <p>This paper presents the results of a comparison between Stokes and Navier-Stokes equations, in order to simulate the flow of liquid water at atmosferic conditions, through a concentric orifice plate. From experimental data taken from the fluids bank, the simulations of both equations were evaluated, using free software Freefem++CS, which is based on the finite elements method. The evaluated variables are velocity and pression in a time interval. When analyzing the results obtained with the simulations and comparing them with the experimental data, it was found that the Navier-Stokes equations represent better the system, than the Stokes equation.</p> ER -
