How to Simulate Impressed Current Cathodic Protection
2 common methods for protecting metal structures against galvanic corrosion are sacrificial anode cathodic protection (SACP) and impressed current cathodic protection (ICCP).
Protecting Against Atmospheric Corrosion with Simulation
Certain environmental factors, such as humidity and snow, can lead to atmospheric corrosion. The result? Rusty bikes, cars, and other metal structures. Simulation can protect against this effect.
Multiphysics Modeling of Stress Corrosion in Underground Pipelines
Stress corrosion is a phenomenon that causes degradation in underground pipelines. Learn how to use multiphysics modeling to understand and predict its occurrence.
Model Electrodes with Nonideal Connectivity in Corrosion Analyses
Learn the appropriate boundary conditions for performing a corrosion analysis in which an electrode is connected to an external short circuit.
How to Model Electrochemical Resistance and Capacitance
Resistive and capacitive effects are fundamental to the understanding of electrochemical systems. The resistances and capacitances due to mass transfer can be represented through physical equations describing the corresponding fundamental phenomena, like diffusion. Further, when considering the resistive or capacitive behavior of double layers, thin films, and reaction kinetics, such effects can be treated simply through physical conditions relating electrochemical currents and voltages. Lastly, resistances and capacitances from external loading circuits can easily be represented in the COMSOL Multiphysics® software.
