Monolithic Reactor

This model simulates the catalytic abatement of a volatile organic compound (VOC), in this case a contaminant in a waste gas. An analytical expression describes the velocity profile in the free channel, while reaction occurs in the washcoat that makes up the tubular shape of the free channel. For simple geometries, the reactor can be described by a 2D model using time as the axial direction ...

Buoyancy–driven μPCR for DNA Amplification

Polymerase chain reaction (PCR) is one of the most effective methods in molecular biology, medical diagnostics, and biochemical engineering in amplifying a specific sequence of DNA. There has been a great interest in developing portable PCR-based lab-on-a-chip systems for point-of-care applications and one strategy that seems very promising is natural convection-based PCR. This model studies ...

Ammonia Synthesis PFR

This example demonstrate the modeling of a plug flow reactor for the synthesis of ammonia in the Haber-Weiss process. The catalytic reactor in this process operates under non-isothermal conditions, where temperature and pressure varies substantially along the length of the reactor, in addition to the variation in composition.

Transport and Reaction in a Catalyst in 3D

Consider the study of a mass balance of a diluted species in air, for example, a pollutant in an exhaust stream. The model’s aim is to calculate the concentration profile of this species, which is decomposed by a catalyst present on the surface of a porous supporting structure. In a first step, you solve the velocity field for the solution assuming that the diluted pollutant has no influence ...
