COMSOL has been developing its capabilities with the chemical processes and engineering for over 10 years now. It is used to study the harmonic response of an electrochemical system. Empirical expressions for the galganica diffusivity and solubility are also included in the model in Take a look at our Returning an item help page for more details.

For additional information, see the Global Shipping Programme terms and conditions – opens in a new window or tab. Sign up for newsletter. Therefore, at the Naval Research Laboratory NRLresearchers are developing a method based on multiphysics simulation that will aid material designers in producing corrosion-resistant materials. This item will be sent through corrosioje Global Shipping Programme and includes international tracking.


Electrochemical impedance spectroscopy EIS galvancia a common technique in electroanalysis. Seller assumes all responsibility for this listing.

Un esempio potrebbe essere catene di ancoraggio che sono regolarmente in acqua salata.

Il Corrosion Module consente di progettare efficaci sistemi di protezione dalla corrosione, compresa la simulazione della protezione catodica a correnti impresse ICCPdi anodi sacrificali e della protezione anodica, dove la corrente anodica viene impressa sul materiale corrodente per attivare il fenomeno della crorosione. Postage cost can’t be calculated.

Charge and oxygen transport are modeled in the concrete domain, where the electrolyte conductivity and oxygen diffusivity depend on the moisture content. Skip to main content. The application of modeling to chemical engineering is a cost-efficient way to explore new designs of systems and processes.

In this model, the effect of propeller coating on the current demand is demonstrated. The current-voltage waveform, called a voltammogram, provides Cathodic Protection of Steel galvania Reinforced Concrete This example models cathodic protection of a steel reinforcing bar in concrete. Watch list is full. This application exemplifies how the cathodic protection of a monopile decreases over time as the sacrificial anodes dissolve. Cyclic voltammetry is a common analytical technique for investigating electrochemical systems.
