A vertical array of corrugated copper plates was tested for its ability to conduct diffusion-controlled liquid-solid reactions. The mass transfer coefficient was investigated in terms of solution velocity, physical parameters of the solution, equivalent diameter of the channel, and array height. It was found that the mass transfer coefficient increases with increasing solution velocity and channel equivalent diameter while decreasing with increasing array height. Compared with flow through flat plates under the same conditions, flow across corrugated-plate channels enhanced the mass transfer rate by a factor of 2–2.72. Dimensionless analysis was used to correlate the mass transfer data. The present work finds wide practical applications in enhancing mass transfer in many processes, such as membrane separation processes, electrochemical processes, heterogeneous liquid-solid catalytic and photocatalytic reactions, and biochemical reactors in which enzymes or microorganisms are immobilized on such corrugated surfaces.

一组分离的平行波纹板的固-液传质

测试了垂直阵列的波纹铜板进行扩散控制的液固反应的能力。根据溶液速度、溶液的物理参数、通道的等效直径和阵列高度来研究传质系数。发现传质系数随着溶液速度和通道等效直径的增加而增加，同时随着阵列高度的增加而降低。与相同条件下通过平板的流动相比，通过波纹板通道的流动将传质速率提高了 2-2.72 倍。无量纲分析用于关联传质数据。目前的工作在增强许多过程中的传质方面具有广泛的实际应用，例如膜分离过程，电化学过程，
