Estudio del flujo del viento en terreno complejo mediante fluido dinámica computacional Cfd para el emplazamiento de una turbina eólica en el parque nacional Chimborazo

Abstract

The present study shows simulations of wind Flow using CFD computational fluid dynamics using the finite volume method, in order to determinate the location with the least turbulence within analyzed area and together the wind potential it presents. For this research process, it was start from previously obtained wind data, such as speeds, standard deviation, pressure, temperatures, etc. First, two study areas were selected to determine the appropriate location taking into account criteria for its sizing, whit this we proceeded to discretize the data for subsequent analysis and determine the conditions of entry and exit of the wind flow, followed by the parameters that represent the study area such as the roughness of the ground, intensity of turbulence and air density. Once the analyzes had been carried out in ANSYS Fluent software with their designated post-processed in VisIt 3.1.4 software, areas with high intensity of turbulence were determined in which the surface did not have wind flow obstructions, determining in this way as a wind site the study area 1 that has a plant capacity factor of 25 percent.
