文中采用计算流体动力学 (CFD)的方法就风口入流紊流参数对通风空调房间内空气流动和分布情况的影响作了数值研究 ,通过对条缝二维平面射流特性及其作为送风口的空调房间室内空气分布的数值计算结果与有关实验数据对比指出 :在相当大的紊流入流参数范围内 ,最终的室内空气流动及平面射流特性的计算结果变化不大 ,藉此可以指导对室内空气流动进行数值模拟时的边界条件描述。
In this paper, CFD method is used to study the influence of air inlet flow turbulence parameters on the air flow and distribution in ventilation and air conditioning rooms. By analyzing the characteristics of two-dimensional plane jet flow and its air-conditioning Comparing the numerical results of indoor air distribution with the relevant experimental data, it is pointed out that the calculated results of the final indoor air flow and planar jet characteristics do not change much in the range of turbulent inflow parameters, which can guide the indoor air flow Boundary conditions for numerical simulation.
