摘　　要：根据高能放电腔的特点以及放电对气体流量、流速和流场的要求,提出了应用于高气压强电离放电的小型低速风洞技术方案。该技术方案在满足流场、流速要求的前提下开展气动设计和结构设计,重点研究了总体结构、气流喷口和收集口的气动与结构设计、动力段气动与结构设计、流速调节控制、电机散热等关键技术。简要介绍了为某单位研制的应用于高能放电的小型风洞。现场应用表明,该小型风洞稳定可靠,是一种实用、有效的高气压高能放电气流循环装置。A kind of small-scale wind tunnel with low-velocity is proposed according to the characteristics of strong ionization discharge chamber and the demands of discharge for flux, velocity and flow fields. On the precondition that the airflow field and velocity is satisfied, aerodynamic design and structural design are carried out. Key techniques are studied including overall structure, aerodynamic and structural design of airflow vent and collection vent, aerodynamic and structural design of power section, flow rate adjustment and control, and cooling system of motor. Based on the design scheme, a small-scale wind tunnel with strong ionization discharge for an enterprise is developed. Application indicates that the small scale wind tunnel is a practical and effective airflow loop device for high pressure and strong ionization discharge with the features of stability and reliability.
