Simulating an Ideal Stirred Tank Reactor System
The Generic CSTR reactor type in the Reaction Engineering interface can be used to easily model continuous stirred tank reactors (CSTRs), or ideal stirred tank reactors.
New and Revamped Chemical Engineering Interfaces
Get an overview of the modeling interfaces for reaction engineering and mass transport in COMSOL Multiphysics®, including the Chemistry and Reaction Engineering interfaces.
Why Car Batteries Perform Poorly in Cold Weather
Have you ever gone to start your car on a cold winter morning and nothing happens? The battery’s ability to convert chemical energy into electrical energy can be affected by low temperatures.
Modeling Approaches in Heterogeneous Catalysis
Get an introduction to heterogeneous catalysis, the main steps for chemical species in heterogeneous catalytic reactions, adsorption-desorption models, surface reactions, and much more…
Electroplating Simulations for Printed Circuit Board Designers
The manufacture of a printed circuit board (PCB) often involves a process called electroplating, which can vary from design to design. A simulation app can make it easy to analyze this process.
Apps for Teaching Mathematical Modeling of Tubular Reactors
Chemical engineering students can use the Tubular Reactor app to model a nonideal tubular reactor and investigate the impact of different operating conditions. Learn more >>
Multiscale Reactors: Cleaning the Flows
Packed bed reactors are used in chemical synthesis and for effluent treatment and catalytic combustion, are often required for heterogeneous catalysis, and commonly include catalyst pellets.
Modeling Hydrodealkylation in a Membrane Reactor
Hydrodealkylation is a hydrogen-intensive process. We demonstrate using the thermodynamics modeling features in the COMSOL® software to analyze this process in a membrane reactor.
