Diseño de un alerón posterior para los autobuses de transporte terrestre interprovinciales mediante el uso de software de simulación CFD para mejorar el gasto de combustible diesel

Abstract

he research of this work was based on the aerodynamic efficiency of the different types of spoilers that can be implemented in a bus to investigate fuel consumption in interprovincial buses, starting from the elaboration of the CAD model in the Inventor program of the Hino AK8JRSA, the most widely used model for the interprovincial passenger land transportation line with the NTE INEN 1668 standards established in Ecuador. With the measures implemented in the CAD design, we proceeded to perform the analysis of the drag coefficient of the bus without a spoiler, to then make three models and implement in the simulation of ANSYS CFX programs with wind variables of 19.44 m / s and 27, 77 m / s on which the study was based. In order to obtain a better result in fuel efficiency, mathematical formulas were used to determine the specific fuel consumption, drag coefficient, Reynolds and simulation analysis with valid percentage error of no more than 15%
