摘要:
对褶型气溶胶过滤器过滤阻力进行理论计算及实验测试.在对速度函数假设的基础上,对Navier-Stokes方程进行压力求解.采用缝隙宽度上压力平均值的概念,提出一个用于求解褶型过滤器过滤阻力的方法,得出褶型气溶胶过滤器过滤阻力的解析解,理论计算结果与实验测试基本吻合.研究表明,减小褶距或增大褶高可增加过滤介质面积,减小过滤器介质过滤阻力; 但是,过滤器结构阻力也将增加,褶型气溶胶过滤器阻力与单位长度褶数存在最佳值.
Abstract:
The theoretical analysis and experiments about filtration resistance of pleated aerosol filter was carried out in this paper.Based on the assumption of the velocity function,the pressure was solved from the Navier-Stokes equation.With the averaged pressure across the local gap width,a model for the overall filtration resistance of pleated air filter and analytical solution was developed.The results of the theoretical calculation were agreed with the experimental results.Reducing the pleat distance or raising the pleat depth produces an increase in the filtration surface,which results an decrease in the medium filtration resistance and an increase in the geometry filtration resistance.There is a optimal pleat nunmber per unit length to make the theoretical filtration resistance minimum.
