室内大空间喷口送风气流组织数值模拟研究
Numerical simulation study on airflow organization of jet supply in large indoor spaces
摘要
Abstract
To address the challenge of regulating the indoor thermal environment in large spaces,an orthogo-nal experimental design and Computational Fluid Dynamics(CFD)simulation were adopted.The Predicted Mean Vote(PMV)was used as the evaluation index to investigate the effects of supply air temperature,sup-ply air velocity,nozzle diameter,and supply air angle on indoor airflow distribution.The results showed that the sensitivity of the parameters ranked as follows:supply air temperature,nozzle diameter,supply air veloci-ty,horizontal angle and vertical angle.For every 2℃increase in supply air temperature,temperature unifor-mity improved by 6.0%to 6.9%.For every 20 mm increase in nozzle diameter,temperature uniformity de-creased by 34.5%to 70.0%.When the supply air temperature was 19℃to 21℃and the nozzle diameter was 194 to 214 mm,the indoor PMV approached the comfort range and the velocity field was more satisfato-ry.Through coordinated optimization,temperature uniformity and airflow stability were improved by 12.7%and 23.5%,respectively.The results indicate that a proper match between supply air temperature and nozzle diameter can effectively improve the indoor thermal environment in large spaces,and provide a quantitative reference for the optimal design and operation control of nozzle air supply systems..关键词
