采用修正的多组分伪势模型( EFM) 模拟了液态法制备金属基复合材料过程中多 孔介质内的浸渗过程，研究了黏度比( M) 、壁面润湿性、雷诺数( Ｒe) 、孔隙率以及不同分 形结构对浸渗过程的影响． 结果表明: 黏度比越大，浸渗饱和度( S) 越低、浸渗时间( t) 越 短，并且 M ＞ 90 时，黏度比对饱和度和浸渗时间影响可忽略不计，此时接触角的影响较 小; Ｒe 越小，浸渗饱和度越高、浸渗时间越长，同时壁面润湿性的影响越大; 当入口 Ｒe 一 定时，孔隙率越小，分形多孔的渗透率越低，由于孔隙分布不均，造成流体在局部优先浸 渗，导致浸渗时间减少、饱和度降低; 对不同的分形多孔介质，壁面润湿性的影响有着明显 的差异，对 A 类( 标准分形) 和 C 类( 固体骨架偏右) 的多孔介质，接触角( θ) 越大，饱和度 越低、浸渗时间越短; 对 B( 固体骨架偏上) 和 D 类( 固体骨架偏左上) 分形多孔，随接触角 的增大，饱和度和浸渗时间均呈现先增加后减小的趋势，并且在接触角小于 90°的区间内 出现极值．

In this paper，the infiltration process of liquid preparation of composite materials has been simulated in porous media by a modified multi-component pseudopotential model ( EFM) ． A study has been conducted of the effects of viscosity ratio ( M) ，wall wettability，Ｒeynolds number ( Ｒe) ，porosity and different fractal structures on the infiltration process． It is shown that the larger the viscosity ratio is，the smaller the infiltration saturation ( S) and infiltration time ( t) will be; meanwhile the effect of viscosity ratio on infiltration saturation and time is negligible when M ＞ 90． At this time the influence of contact angle is very small; the smaller the Ｒe is，the greater the infiltration saturation and infiltration time are，and the greater the effect of wall wettability will be． When the Ｒe of inlet is consistent，the smaller the porosity is，the lower the permeability of the fractal porous will be． Due to the uneven pore distribution，the fluid preferentially infiltrates in local area，leading to the decrease of the infiltration time and the saturation． For different fractal porous media，the influence of wall wettability is obviously different． For Type A ( standard fractal) and Type C ( right deviation of solid matrix) porous media，the larger the contact angle ( θ) is，the saturation and the infiltration time is smaller． The fractal porosity of type B ( upward deviation of solid matrix) and D ( left deviation of solid matrix) fractal porous，the larger the contact angle is，the saturation and the infiltration time tend to increase firstly and decrease lately，and the extreme value appears in the contact angle which is less than 90°．
