Computational electrochemistry simulations of homogenous chemical reactions in the confluence reactor and channel flow cell

Article Abstract:

Homogenous chemical kinetics research using hydrodynamic devices is successfully used in the study of mechanisms and rates of complex electrochemical processes. Use of the finite element method to simulate steady-state convection diffusion problems is presented for EC, ECE and DISP reactions.

Steady-state voltammetry using microwire electrodes under microfluidic control

Article Abstract:

The development and applications of a new hydrodynamic electrochemical device is described and finite element simulations are presented to model the solution velocity profiles within the cell and around the microwire electrode. The results of these calculations were employed to characterize the concentration distribution of a reactant within the cell, which is undergoing a transport-limited reaction at the electrode/solution interface.

Computational electrochemistry: The simulation of voltammetry in microchannels with low conductivity solutions

Article Abstract:

An approach based on finite element method (FEM) to solve the relevant fluid dynamic, mass transport and potential distributions in three dimensions to reveal quantitative information on the voltage response is presented. The effect on the voltage curve of using a range of reference electrode positions is investigated.
