Example Models

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....

A 3D Model of a Diesel Particulate FilterA 3D Model of a Diesel Particulate Filter

Several factors influence a diesel particulate filter’s (DPF) efficiency and durability. Important issues include the removal of soot particles from the filter membranes and the influence of thermal stress on the ceramic structure,...

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...

Hydrocarbon Dehalogenation in a Tortuous MicroreactorHydrocarbon Dehalogenation in a Tortuous Microreactor

Removing halogen groups from hydrocarbons is an important reaction step in several chemical processes. One application is water purification. Other examples involve organic synthesis, where the removal of halogen groups serves as a...

Steam ReformerSteam 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...

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...
