摘要
本文首次用三维数值模拟计算的方法结合风洞实验研究了厢式货车表面气流的流动特性。揭示了气流流动特性和厢式货车气动阻力特性之间的关系 ;厢式货车基本结构参数变化时阻力特性的变化规律。为厢式货车的气动造型设计提供了重要参考依据。
In this paper, the surface airflow characteristics of a van body truck were investigated by means of the 3 D numerical simulation combined with wind tunnel experiments for the first time. The relationship between airflow characteristics and aerodynamic drag and the variation of aerodynamic drag with basic structural parameters were obtained. The research results can render important reference for aerodynamic shape designing of van body truck.
