This tutorial example serves as an introduction to the Corrosion Module and models the metal oxidation and oxygen reduction current densities on the surface of a galvanized nail, surrounded by a piece of wet wood, which acts as electrolyte. The protecting zinc layer on the nail is not ... En savoir plus
For several high-precision applications, especially in hydraulic systems and fuel injectors, micro bores are needed. In most cases the shape of the injection hole, especially the edge rounding, has a significant influence on the atomization of fluids and therefore on the combustion ... En savoir plus
In this set of eight tutorial models and associated documentation, you can investigate the resistive, capacitive, inductive, and thermal properties of a standard three-core lead-sheathed XLPE HVAC submarine cable with twisted magnetic armor (500 mm2, 220 kV). The series includes a 2D, 2D ... En savoir plus
This app demonstrates the usage of a surrogate model function for predicting the rate capability of an NMC111/graphite battery cell. The rate capability is shown in a Ragone plot. The surrogate function, a Deep Neural Network, has been fitted to a subset of the possible input data ... En savoir plus
Aldicarb is a commercial pesticide, used on a variety of crops, including cotton, fruits, potatoes, and beans. This arises in the possibility that the general population may be exposed to aldicarb through the ingestion of contaminated water and foods. This example looks at the ... En savoir plus
This model simulates atmospheric galvanic corrosion of an aluminum alloy in contact with steel. The electrolyte film thickness depends on the relative humidity of the surrounding air and the salt load density of NaCl crystals on the metal surface. Empirical expressions for the oxygen ...

Gas cells have several applications in the design of scientific instruments. A gas cell is used to define a high-pressure region within the instrument's main vacuum system. For example, in this application, note we are designing a high-pressure region 100 mm long, with an operating ... En savoir plus
Copper electrowinning is the process of copper extraction from an electrolyte solution and its deposition at the cathode surface, by passing an external current through the electrolytic cell and using an insoluble anode. During the process, oxygen bubbles are generated at the anode ... En savoir plus
This tutorial models an ICP reactor by solving plasma fluid type equations fully coupled with the homogeneous and time-independent electron Boltzmann equation in the classical two-term approximation. The approximated Boltzmann equation is solved for each position of space and is coupled ... En savoir plus
In this example, a heterogeneous NMC (Nickel-Manganese-Cobalt) electrode structure is generated from tomography data using a Model Method. Time-dependent discharge and electrochemical impedance spectroscopy (EIS) simulations are then made on the full 3D geometry. A solid mechanics ... En savoir plus
