Qualitative Verification of Active/Passive Aerodynamic Improvements of Aero-Car

摘要

The main point of this paper is to investigate the qualitativernverification of aerodynamic improvements of Aero-car. The active andrnpassive improve methods are all considered. The advanced smoke flowrnvisualization system is the main means to verify the vortical structures at thernbackside. The wake flow, which often causes resistance, is producedrnbecause of original structure. The purpose of the aerodynamic improvementrnin this study is mainly to eliminate or reduce the impact of this kind ofrnstructure. Results reveal the size of wake flow is smaller and the structure isrnalso delay to develop. It is helpful for reducing fuel consumption, enhancingrnflight performance and increasing flight speed.
