异形纤维过滤器流场及阻力数值分析模型

Analysing model for the flow field and drag of fibrous filters with noncircular fibers

介绍一个分析异形纤维过滤器流场和阻力模型，通过求解完全的Ｎ－Ｓ方程获得方形纤维矩形模型过滤器内的流场和阻力，与其它方法所获得的结果相比，该方法所获得的流场更具合理性，可用于过滤器内浓度场的计算．

A model for analysing the drag behaviours of fibrous filters with noncircular fibers is introduced.The flow field and drag are acquired by solving N S formula with SIMPLE method.comparing with other methods,it is more reasonable and can be used to calculate the dense field in a filter.
