| 摘 要： | 提出了用ＣＦＤ法求解空气龄的具体方法，其步骤为先求解Ｎ－Ｓ方程，后求解空气龄。为求解Ｎ－Ｓ方程，采用了改进型ＨＳＭＡＣ法，并给出了压力和速度同时修正的方法。为求解空气龄，推出了空气龄输送方程式和给出了空气龄和速度成分的边界条件。计算机模拟验证了求解方法的有效性并由空气龄求出了通风效率。

| Abstract: | A method for solving age of air is given by CFD . The Navies Stokes equations are first solved, and then the age of air equation. For solving the Navies Stokes equations, the revised HSMAC method is used, and updated method for pressure and velocity component is given. For solving age of air, the transport equation of age of air is derived, and the boundary conditions for age of air and velocities are set up. The computer simulation confirmed the availability of this method and the ventilation efficiency is obtained based on age of air. |
