中文摘要: 设计了一座试验段当量直径为1.5m, 试验段长度为2.0m, 最高实验风速为50m/s的低速开口回流风洞.采用三维建模软件和计算流体力学软件, 对风洞的流场品质进行数值计算.气动设计过程表明, 收缩比、收缩曲线线形、蜂窝器、紊流网对流场品质有较大的影响.
Abstract:A test section of the equivalent diameter of 1.5m test section length of 2.0m, the highest experimental wind speed of 50m/s low-speed open return wind tunnel is designed.By using 3D modeling and computational fluid dynamics software, flow field quality is calculated by the numerical calculation.Aerodynamic design shows contraction ratio, contraction curve linear, cellular device, turbulent mesh has a greater impact on flow field qualities
