孔板空调风口送风射流的数值模拟

NUMERICAL SIMULATION OF AIR JET FROM PERFORATED PANELS

  • 摘要: 介绍N点风口模型用于数值模拟室内空气流动时描述孔板类送风口的入流边界条件. 然后采用该风口模型对不同的孔板风口出流条件算例进行数值计算,并就轴心速度衰减、射流扩展角以及断面流速分布等射流特性与实验数据进行了对比. 比较结果表明,N点风口模型用于描述数值模拟室内空气流动的孔板类风口入流边界条件,可以获得工程上足够满意的结果.

     

    Abstract: A new method called N-point supply opening model for describing inlet boundaryconditions of indoor airflow simulation is proposed to deal withperforated panels. Examples of two perforated panels under various inlet velocities are presented.Both the simulated results and experimental data of centerline velocity distribution, angle ofdivergence and jet velocity profile are discussed. Comparisons between predicted results andexperimental data show that the new approach can well describe those rather complicated inletboundary conditions of perforated panel in the indoor airflow simulation.
