This model simulates the shape evolution of a microconnector bump over time as copper deposits on an electrode surface. Transport of cupric ions in the electrolyte occurs by convection and diffusion. The electrode kinetics are described by a concentration dependent Butler-Volmer ... 詳細を見る
A monopile foundation is a large-diameter structural element that can be used to support structures like offshore wind turbines. This application exemplifies how the cathodic protection of a monopile decreases over time as the sacrificial anodes dissolve. The model can be used to ... 詳細を見る
This 2D model demonstrates how to model a galvanic couple in which the corrosion of the anode causes a geometry deformation. The parameter data used is for an Magnesium Alloy (AE44) - mild steel couple in brine solution (salt water). 詳細を見る
Streamers are transient filamentary electric discharges that can develop in a nonconducting background in the presence of an intense electric field. These discharges can attain high electron number density and consequently a high concentration of chemical active species that are relevant ... 詳細を見る
This model verifies that the onset of streamer formation between two spheres separated by atmospheric pressure dry air at a distance of 2cm occurs at 51.8kV. The electrical breakdown is detected by integrating Townsend coefficients along the electric field lines between the two spheres. ... 詳細を見る
This example investigates the electrical and thermal characteristics of a plasma DC arc created in a point-to-plane configuration. The discharge is assumed to be in local thermodynamic equilibrium. The plasma is considered a conductive fluid medium and is modeled using a ... 詳細を見る
This example treats the modeling of electroosmotic flow in porous media. The system consists of a compartment of sintered porous material and two electrodes that generate an electric field. The cell combines pressure and electroosmotic driven flow. The equations that are solved are the ... 詳細を見る
The purpose of the app is to demonstrate and simulate the use of cyclic voltammetry. You can vary the bulk concentration of both species, transport properties, kinetic parameters, as well as the cycling voltage window and scan rate. Cyclic voltammetry is a common analytical technique ... 詳細を見る
Electroless deposition or plating is a non-galvanic plating method that does not require any external electrical power. This technique is typically used for electroless plating of nickel, silver, gold and copper. In electroless deposition, partial oxidation and reduction reactions ... 詳細を見る
A fuel cell unit cell is modeled using the full Butler-Volmer expression for the anodic and cathodic charge transfer reactions. The anodic and cathodic overpotentials depend on the local ionic and electronic potentials, which are obtained from the charge balance equations for ionic and ... 詳細を見る
