DESIGN OF THE AERODYNAMIC TUBE TO DETERMINE THE AIR-FORCE RESISTENCES AFFECTING TO THE MOVING VEHICLE

Abstract

This paper presents the study of increasing the performance of aerodynamic of the HaUI-EV1 electric vehicle. The car body model, firstly, was initially designed and simulated aerodynamic with CFD. To evaluate and analyze the simulation results, it was required to have a laboratory model of instrumentation and testing the actual aerodynamics parameters. Therefore, an aerodynamic tube has been designed and constructed to determine the air-force resistances affected to the vehicle during the movement such as the drag and lift forces. This aerodynamic tube should be designed to meet the technical requirements such as the maximum flow velocity of the air within the pipe; tube size and scale of the experimental model; the accuracy of the measurement results; obstruction of airflow. The results of the article must be the major factors for the designing, manufacturing, testing and optimizing the aerodynamic characteristics of the HaUI-EV1’s body.
