An Original Aerodynamic Ducting System to Improve Energy Efficiency in the Automotive Industry

Abstract

In the automotive industry, the flow of air generates high resistance in the advance of vehicles. In light of this situation, the objective of the present invention is to take advantage of the force of the air itself to help propel vehicles and thus reduce fuel consumption. A channeling system has been designed based on a deflector that collects the air that impacts against the vehicle at the front, transferring it to the rear where it is expelled, allowing the vacuum zone to be filled so that the high pressures of the channeled air are repositioned in the depression zone, significantly increasing the values of the pressures, including those that were previously negative. The deflector has been built and incorporated into a model car so that comparative experimental wind tunnel tests could be carried out to verify that the vacuum in the rear area is eliminated, and positive pressure is obtained.

Open-Loop Subsonic Suction Type Wind Tunnel: Design, Simulation, Build and Test

“…In the building sector, a boundary layer wind tunnel is commonly used to simulate the flow around tall buildings and to study the wind load effect of façade, the arrangement of buildings, and their responses [11][12][13][14][15][16]. Nevertheless, the study of micro air vehicles [17], airfoils [18][19], and automobiles can also be performed in a wind tunnel [20][21].…”
