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).
Taking a Look at Electrochemical Treatment for Tumors via Modeling
EChT offers many benefits for the treatment and removal of cancerous tumors, so why isn’t it a widely accepted method yet? First, we need a better understanding of tumor destruction mechanisms.
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.
Modeling Electrodes and External Short Circuits 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.
The Boundary Element Method Simplifies Corrosion Simulation
As of version 5.4 of the COMSOL Multiphysics® software, there are features for simulating corrosion in slender structures. This significantly speeds up the total time spent when working with structures such as oil platforms. By using the boundary element method (BEM) and specialized beam elements in the Current Distribution, Boundary Elements interface, there is no longer a need for a finite element mesh to resolve the whole 3D structure, saving time for large corrosion problems consisting of slender components.
