微型低湍流度直流风洞的气动设计

Aerodynamic Design of the Mini Low Turbulence Open-circuit Tunnel

风洞实验是进行空气动力学研究的重要手段。通过对低湍流风洞的调研分析,设计了一座具有先进指标的微型低湍流度低速风洞,设计过程中,对收缩段、稳定段等湍流主要影响部件给出了详细的气动设计依据。风洞建成后,配合其他设备可以进行航空航天、桥梁建筑、交通运输等专业的空气动力学教学实验。

Wind tunnel experiment is the important method in the field of aerodynamic.Based on intensive investigation and analysis of low-turbulence wind tunnel,the mini wind tunnel,which has excellent performance,in low turbulence has been designed and built.Aerodynamic design of the main parts,including contraction section,stable section and other main influence parts for decrease turbulence,are described in detail.The wind tunnel can be used for aerodynamic teaching experiments in aeronautics and astronautics,building and bridge construction and transportation.
