Thermal Decomposition

In this tutorial, the heat and mass transport equations are coupled to laminar flow in order to model exothermic reactions in a parallel plate reactor. It exemplifies how you can use COMSOL Multiphysics to systematically set up and solve increasingly sophisticated models using predefined physics interfaces.

Biosensor Design

Surface reactions with adsorption-reaction-desorption steps are common in for example photocatalysis and biosensors. A flow cell in a biosensor contains an array of micropillars for adsorption of for example antigens in aqueous solutions. A signal proportional to the surface coverage can be detected in a sensor, for example through chemiluminescence. This demo app features a flow cell with ...

Microchannel H-Cell

This example was originally formulated by Albert Witarsa under Professor Bruce Finlayson’s supervision at the University of Washington in Seattle. It was part of a graduate course in which the assignment consisted of evaluating the potential of patents in the field of microfluidics through mathematical modeling. The model treats an H-micro cell for separation through diffusion. The cell puts ...

Carbon Deposition in Heterogeneous Catalysis

Carbon deposition on the surface of solid catalysts is commonly observed in hydrocarbon processing. A known problem is that carbon deposits can impede the activity of catalysts as well as block the flow of gas through a catalyst bed. This example investigates the thermal decomposition of methane into hydrogen and solid carbon, over a catalyst. The influence on the catalyst activity is first ...

Multicomponent Tubular Reactor with Isothermal Cooling

This application uses the Chemical Reaction Engineering Module to study an elementary, exothermic, irreversible reaction in a tubular reactor (liquid phase, laminar flow regime). To keep its temperature down, the reactor uses a cooling jacket with a constant coolant temperature. The steady-state behavior of the reactor is investigated. The application visualizes how the Chemistry and Transport ...

Steam Reformer

In fuel cell power generators, a steam reformer unit typically produces the hydrogen needed for the cell stack. This example illustrates the modeling of a steam reformer. The reformation chemistry occurs in a porous catalytic bed where energy is supplied through heating tubes to drive the endothermal reaction system. The reactor is enclosed in an insulating jacket. The tightly coupled ...

Dissociation in a Tubular Reactor

Tubular reactors are often used in continuous large-scale production, for example in the petroleum industry. One key design parameter is the conversion, or the amount of reactant that reacts to form the desired product. In order to achieve high conversion, process engineers optimize the reactor design: its length, width and heating system. An accurate reactor model is a very useful tool, both at ...

Drug Release from a Biomaterial Matrix

In this example, drug-release from a biomaterial matrix to damaged cell tissue is modeled. Specifically, a nerve guide delivers a regenerating drug to damaged nerve ends. The model involves detailed drug release kinetics, with rate expressions handling drug dissociation/association reactions as well as matrix degradation by enzyme catalysis. The enzyme reaction is described by Michaelis-Menten ...

Transport in an Electrokinetic Valve

This application presents an example of pressure driven flow and electrophoresis in a 3D micro channel system. Researchers often use a device similar to the one in this model as an electrokinetic sample injector in biochips to obtain well-defined sample volumes of dissociated acids and salts and to transport these volumes. Focusing is obtained through pressure driven flow of the sample and ...

Ideal Stirred Tank Reactor System

In the chemical and biochemical industries, for instance in fermentation processes, reactors having well-mixed conditions and liquid level control are common. This example shows modeling of a 0D ideal system of tank reactors in series with controlled feed inlet and product outlet streams. The volume change in each reactor is monitored as well.
