三种规整填料（Mellapak 250 Y、Mellapak 500 Y和Mellapac 1 Y）的有效传质面积（ae）通过在0.427 m ID柱中的化学吸收测量，作为液体负荷（1-30 gpm/ft 2或2.4-73.2 m3/m2.h）、液体粘度（1--15 mPa.s）和表面张力（30-72 mN/m）的函数。粘度没有影响，表面张力对有效面积只有微弱的影响。对于整个实验数据库，有效面积与比表面积的比率（ae/ap）作为液体韦伯数和弗劳德数的函数在±15%的限度内相关：
The effective mass transfer area (ae) of three structured packings (Mellapak 250Y, Mellapak 500Y, and Flexipac 1Y) was measured via chemical absorption in a 0.427 m ID column as a function of liquid load (1–30 gpm/ft2or 2.4–73.2 m3/m2.h), liquid viscosity (1−−15 mPa.s), and surface tension (30–72 mN/m). Viscosity had no effect and surface tension had only a weak effect on the effective area. The ratio of effective area to specific surface area (ae/ap) was correlated as a function of the liquid Weber and Froude numbers within limits of ±15% for the entire experimental database:
