| 摘 要： | 假定室内通风气流是二维、稳定、不可压缩的粘滞紊流流动，以流函数、涡度和紊流能量为循环计算变量，用定常方法进行数值模拟。文中介绍了基本方程及它们的离散化、边界条件的设定，给出了计算实例并对紊流和层流两种模型的数值模拟作了简要的比较。

| Abstract: | The indoor ventilation airflow is supposed to be two-dimensional, steadystate,incompressible and viscose turbelente flow. The stream function,the vorticity and theturbelente energy are taken as the cyclic computational variables and the steady method isused to obtain the numerical simulation. Basic equations and their discretion, thedetermination of boundary conditions, numerical simulation examples and the comparisionbetween two different models of turbulente and laminar flow are presented in the currentpaper. |
