Determination of mass transfer coefficient of a cross-corrugated membrane reactor by the limiting-current technique

We report mass transfer coefficient correlations, at low Reynolds numbers for a novel cross-corrugated membrane reactor, which is being developed for a number of processes, most notably phase-transfer catalysed reactions. The presence of Tollmien–Schlichting (T–S) waves saw a noticeable enhancement...

Description
Summary:We report mass transfer coefficient correlations, at low Reynolds numbers for a novel cross-corrugated membrane reactor, which is being developed for a number of processes, most notably phase-transfer catalysed reactions. The presence of Tollmien–Schlichting (T–S) waves saw a noticeable enhancement in mass transfer, giving characteristics usually only found in turbulent flow. Correlations for the channel wall and the channel corrugations are given in terms of dimensionless Sherwood numbers: Sh CW =0.0209Re 0.7675Sc 0.333 (200
