摘　　要：为了提高地铁通风系统送风风道出风均匀性,改善乘客的乘车舒适性及空气质量,采用CFD仿真软件Fluent对地铁送风风道内气流组织分布特点及出风均匀性进行研究。结果表明,原始结构下风道内局部涡旋明显,出风均匀性较差。对高、矮风道送风量及在风道内部设置导流板,使出风均匀性提高约60.4%,并通过调整导流板的位置及尺寸,进一步改善低风道的出风均匀性。In order to improve the uniformity of air supply in subway ventilation systems and enhance passenger riding comfort and air quality, the CFD simulation software Fluent is adopted to study the characteristics of airflow organization and the uniformity of air supply in subway air ducts. The results show that under the original structure, local vortices in the ducts are obvious, and the uniformity of air supply is poor. By adjusting the air supply volume of high and low ducts and setting guide plates inside the ducts, the uniformity of the air supply is improved by about 60.4%. Furthermore, the uniformity of the air supply in low ducts is further improved by adjusting the position and size of the guide plates.
