Análisis de instrumentación y simulación de un túnel de viento subsónico de ciclo abierto

Abstract

The present work selects and apply a correct and low cost instruments system for the wind tunnel located in the “Escuela Politecnica Nacional del Ecuador” at the fluid mechanic and turbomachinery laboratory. With this instrument the static pressure over an aerodynamic profile NACA 2412 is evaluated and compared with a parametric model in Xfoil and a CFD numeric simulation of the same profile. The experiment is evaluated at Reynolds of with increasing angles from -5 to 15 degrees. The CFD simulations were performed using ICEM structured mesh and experimental boundary conditions at the same angles. The validations of the experimental results are determined with the error of the experiment, parametric and CFD comparison.
