摘要
机舱内部气流组织及污染物传播的研究对于创造舒适和健康的机舱环境是十分重要的。为了快速地得到机舱内部气流分布及污染物传播规律,选用COwZ模型。它是多区域模型的一种,应用4排座机舱模型对COwZ模型进行了模型验证。把模拟结果与实验值进行比较,气流组织与实验测的的趋势符合,大部分实验测量点污染物无量纲比值的相对误差率在25%以内,得出结论 COwZ预测机舱环境是可行的。
The study of airflow and contaminant transport in airliner cabins is very important for creating a comfortable and healthy environment.To know how the air and contaminants are distributed and transported in the whole air cabins fast.A zonal model called COwZ is chosen.This study validates the COwZ model using data from a mockup cabin in the literature,The numerical results are compared to the experiment data.The air distribution could reflect the flow trend approximately.Most of the measure points whose non-dimensional(SF6) concentration profiles are with an error less than 25%.The results indicate that COwZ model is practicable for simulating airlinecabin environment.
