Abstract
GUERRA-MAZO, Miryam Lucía; GARCIA-BUITRAGO, María Vilma and RODRIGUEZ-ACEVEDO, Elizabeth. Comparative study of fluid flow across orifice plate using Stokes and Navier-Stokes equations. Rev. Fac. ing. [online]. 2016, vol.25, n.42, pp.99-110. ISSN 0121-1129.
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.
Keywords : mathematical model; orifice plate; simulation; Stokes and Navier-Stokes equations.
