Due to the heterogenous nature of electrochemical reactions, mass transport is an important consideration during reaction and reactor development. The effect of different flow channel geometries on mass transfer between wall and solution within a continuous electrochemical reactor has been investigated using experimental studies and computational fluid dynamics. The channel shape is shown to have modest impact on the mass transfer coefficient. However, the reaction solution hopping from one side of an electrode to the other, so switching polarity mid-flow, has the greatest effect.

步骤、跳跃和转弯：检查通道形状对连续电化学反应器中传质的影响

由于电化学反应的异质性，质量传递是反应和反应器开发过程中的一个重要考虑因素。已经使用实验研究和计算流体动力学研究了不同流道几何形状对连续电化学反应器内壁和溶液之间传质的影响。显示通道形状对传质系数有适度的影响。然而，反应溶液从电极的一侧跳到另一侧，因此在流动中切换极性具有最大的效果。
