摘要
为简化风口入流边界条件的描述 ,提出用N个简单开口代替不同方向出流的百叶风口 ,建立了N点风口模型 ,据此模型对不同出流条件的百叶风口射流进行了数值模拟 ,并就轴心速度衰减、射流扩展角及断面流速分布等与实验数据进行了对比。结果表明 ,当N =1或3时 ,模拟结果令人满意。
To simplify the description of inlet boundary conditions of indoor airflow simulation puts forward N -point supply air outlet model instead of diverse direction airflow of the register. Presents the examples under varied inlet velocities and directions. Discusses the simulated results and exmperimental data of the axial velocity decay, angle of divergence and jet velocity profile. Comparisons between predicted results and experimental data show that when N is equal to one or three, the simulated results are satisfactory.
