The files named Cell1data, Cell2data, and Cell3data contains 20 worksheets for the 3 studied cases cell1 = the original electrolyte flow compartment cell2 = the first 3D printed electrolyte cell compartment under study cell3 = the second 3D printed electrolyte cell compartment ****************************************************************** The first 10 green-tab-worksheets presented at each one of the "CellXdata.xlm" files correspond to the 10 different distributions carried out at various electrolyte flow velocities ranging from 10-100 dm^3 h^-1 Each one of these worksheets has various columns column A the time vector column B-U the voltage drop signal measured at each one of the oval electrodes acording to the upper diagram shown in figure 7 from the paper. ****************************************************************** The second 20 worksheets correspond to the potentiostat data that was applied between the working electrode (the end connection of the 20 oval electrodes and the other copper plate counterelectrode). This is the experimental data controlled using the autolab potentiostat, these worksheets have a yellow tab. Column C is the time vector, Column D is the applied potential Column E is the total current measured There are 10 worksheets each one correspond to a different electrolyte flow velocity ranging from 10-100 dm^3 h^-1. From these yellow tabs the figures shown in Figure 6 from the paper can be obtained. ******************************************************************* The plots shown in figure 7 can be obtained by adding up the 20 Voltage signals from the green tabs and by comparing them with the total current measured (yellow tab) this have to be compared in the same current flow conditions (i.e. case 10 dm^3 h^-1 green tab with case 10 10-100 dm^3 h^-1 yellow tab). The ratio give the resitance (scale factor). Once that factor is know from the 20 voltage signals is possible to determiner the 20 current signals at each electrode. by taking the average value of the current at each of the 20 electrodes and dividing it by the average value of each individual oval electrode for each one of the cases the plots shown in figure 7 can be obtained for each one of the 3 cells. ******************************************************************** In the file named pressuredropandmasstransfer.xls the data corresponding to figure 9 and 10 is plotted. ******************************************************************** Finally in the file named "dataforsurfaces" data the vertex values for the J/Javg values are presented. ******************************************************************** Any further information can be asked to hafr1g13@soton.ac.uk capla@soton.ac.uk Kind regards Horacio Figueredo
