Electroplating Simulations for Printed Circuit Board Designers

December 17, 2014

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

November 21, 2014

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

November 3, 2014

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

October 27, 2014

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.
