One of the most common reactors in the chemical industry, for use in heterogeneous catalytic processes, is the packed bed reactor. This type of reactor is used both in synthesis as well as in effluent treatment and catalytic combustion. This model is set up to calculate the ... En savoir plus
This example illustrates the principle of wet chemical etching for 2D geometry under laminar flow. The purpose of this tutorial is to examine how the copper substrate material is depleted and how the cavity shape evolves during the wet etching process. Wet chemical etching is ... En savoir plus
Plate reactors running under continuous conditions have emerged as candidates to replace batch reactors, primarily in fine chemicals and pharmaceuticals production. One of the advantages of the plate reactor design is that it allows for efficient temperature control of the reacting ... En savoir plus
This example models a split-and-recombine mixer channel in which a tracer fluid is introduced and mixed by multilamination. Diffusion is removed from the model using an extremely low diffusion coefficient so that any numerical diffusion can be studied in the lamination interfaces. The ... En savoir plus
In microfluidic devices, it is a challenge to mix different fluids. One method is to use acoustic streaming to create a flow which enhances the mixing of two fluids. In this model, the vibrations of PDMS structures in a channel induces fast acoustic streaming used for mixing a diluted ... En savoir plus
Chemical vapor deposition (CVD) allows a thin film to be grown on a substrate through molecules and molecular fragments adsorbing and reacting on a surface. This example illustrates the modeling of such a CVD reactor where triethyl-gallium first decomposes, and the reaction products ... En savoir plus
Microlaboratories for biochemical applications often require rapid mixing of different fluid streams. At the microscale, flow is usually highly ordered laminar flow, and the lack of turbulence makes diffusion the primary mechanism for mixing. While diffusional mixing of small ... En savoir plus
In this model, the effect of corrosion product on galvanic corrosion between a magnesium alloy (AE44) and mild steel in contact with brine solution is presented, wherein deformed boundaries due to both deposition of corrosion product as well as dissolution of magnesium are considered. ...

This application shows how mass transfer out from a thin 3D domain can be approximated using a 2D component with the domain feature Out-of-Plane Flux. This feature is useful when the concentration gradient in the out-of-plane direction (along the thickness) is small, and decreasing the ... En savoir plus
Rotating cylinder Hull cells are an important experimental tool in electroplating and electrodeposition and are used for the measurement of nonuniform current distribution, mass transport, and throwing power of plating baths. The model reproduces the results for a commercially available ... En savoir plus
