摘要
对纤维聚结分离流场进行了数值模拟研究。结果表明,纤维聚结分离器的压力场由前到后呈现缓慢降低的分布,随着厚度的增加压力变小;聚结模块压降随着流速、厚度的增加而线性增加,随着孔隙率的减小而增加;纤维聚结分离器的速度场呈现对称式分布,流体在流进纤维层时明显加速,最大速度出现在纤维的间隙中,在纤维间隙中速度呈现"M"形分布。
A numerical study was conducted for the research of the fiber coalescence separation flow field.The results show that the pressure field of the fiber coalescence separator shows a slowly decreasing distribution from front to back.The pressure decreases with the increase of thickness.The coalescence pressure drop increases linearly with the increase of flow velocity and thickness.With the increase of porosity,the velocity distribution of the fiber coalescence separator is symmetrical.When the fluid flows into the fiber layer,The maximum velocity occurs in the fiber gap.The distribution of velocity in the fiber gap presents a"M"shape.
