Fully-coupled Physics with Joule Heating, CFD and Chemical ReactionsFully-coupled Physics with Joule Heating, CFD and Chemical Reactions

In this example, a fluid carrying several chemical components is pumped into a detector compartment. A wire in the center of the detector is heated through Joule heating, which is supposed to detect changes in density through convective...

Chemical Reactions and Soot Build-up in a Diesel FilterChemical Reactions and Soot Build-up in a Diesel Filter

In this model, a filter system for a diesel engine is modelled, including where a soot layer builds up and is oxidized. The build-up of the layer is held in check by both catalytic and non-catalytic reactions, where carbon is oxidized to...

Polymerization in a Multijet Tubular ReactorPolymerization in a Multijet Tubular Reactor

This example considers condensation polymerization in a tubular reactor, where mixing in the reactor is achieved by impinging turbulent jets of reactants onto each other. Turbulent flows involving rapid reaction kinetics are quite...

Carbon Deposition in Heterogeneous CatalysisCarbon Deposition in Heterogeneous Catalysis

Carbon deposition onto the surface of solid catalysts is commonly observed in hydrocarbon processing. Carbon deposits can affect both the activity of catalysts as well as the flow of gas through a catalyst bed. This example...

Chemical Vapor Deposition of GaAsChemical Vapor Deposition of GaAs

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...

NOx ReductionNOx Reduction

This model treats the selective catalytic reduction of NOx in an exhaust gas stream. The reaction takes place on the catalytic surface of a monolith reactor. A first simulation models the monolith channel as a plug-flow reactor. A...

Pesticide Transport and Reaction in SoilPesticide Transport and Reaction in Soil

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...

DNA DegradationDNA Degradation

In gene therapy, plasmid DNA (pDNA) can express desired proteins in the human body. A major issue in gene therapy consequently involves the transport of pDNA to target sites and the conversion between different forms of this species....

Ozone CombustionOzone Combustion

This 1D example illustrates the detailed modeling of a premixed, laminar, steady-state flame where ozone undergoes combustion to form oxygen. The chemical degradation of ozone is described by seven reversible, elementary reactions....

Chemical Equilibrium in a Protein Adsorption Ion-exchangerChemical Equilibrium in a Protein Adsorption Ion-exchanger

This example uses algebraic equilibrium relations to model the time-dependent adsorption of proteins to an ion-exchange medium. The fluid phase contains three components: two proteins and one salt. The adsorption/desorption kinetics...
