This repository contains dataset and Python script for the publication entitiled "Effect of Pulsatile Flow and 3D-Printed Electrodes on Mass Transport and Pumping Power in Electrochemical Reactors".Abstract Enhancing the performance of electrochemical reactors has received substantial attention, but studies on mass transport enhancement by pulsatile flow and its associated power consumption remain unknown. The effects of net electrolyte flow rate, pulsation frequency, pulse amplitude, and geometry of 3D printed electrodes on mass transport and pumping power were studied and compared against conventional steady state flow. The limiting current was measured to calculate the volumetric mass transport coefficient based on the copper deposition reaction on 3D-printed stainless steel electrodes. The pumping power density of different electrode geometries, including Body-centred cubic, Octahedron, and Baffle designs, was determined from the oscillatory pressure drop and oscillatory flow rate. Body-centred cubic with a unit cell size of 1.25 mm and Baffle electrode geometries showed a clear enhanced mass transport relative to steady state flow at higher pumping power density. The highest measured mass transport was achieved by the Body-centred cubic electrode, with a maximum improvement of approximately 30% over steady state flow. Pulsatile flow was shown to increase mass transport at the same pumping power, indicating that it is a viable strategy for improving the performance of electrochemical reactors.
