摘要:
基于室内零方程湍流模型,利用水平贴附射流原理,改变小微空间的送风口位置,进行三维数值模拟,分析不同情况下的温度场和速度场分布;利用不均匀系数、通风效率和空气龄值指标对气流组织效果进行评价,得出最佳风口布置位置.通过计算,发现对于小空间,送风口位置的变化对投入能量利用系数的影响不大,对不均匀系数影响较大.
Abstract:
Based on indoor zero equation turbulence model and horizontal wall attatched jet princeple, by changing the position of air diffuser in small micro space, and using three-dimensional numerical simulation, temperature and velocity distribution under different conditions were analyzed. Uniformity coefficient, ventilation efficiency and mean age of air are used to evaluate airflow effect, and obtain the optimum diffuser layout. The results of calculation show that changing the position of air outlet has little effect on ventilation efficiency, but greater effect on energy utilization coefficient.
