Modeling Fermentation in Beer Brewing Yields a Better Product
Behind every glass of beer is a series of steps that deliver its unique taste. Fermentation, the process during which sugars are converted into alcohol, is one of these important steps. With the help of COMSOL Multiphysics, we can study the fermentation process, identifying ways to optimize its efficiency and serve up a better-tasting beer.
Protein Adsorption: Batch and Space-Dependent Modeling
When studying a system’s chemical kinetics, it’s common to use perfectly mixed batch reactor assumptions and design experiments that keep mixing conditions ideal. Such assumptions include perfectly mixed (ideal tank reactors) and perfectly unmixed (ideal plug flow reactors). In reality, however, it’s rare that all of the reactor’s parts behave the same way. Space-dependent modeling is thus essential in understanding and optimizing chemical reactors. Let’s explore the development of a detailed reactor model, starting with a simple perfectly mixed example.
Using Simulation in the Race Against Corrosion
Corrosion is one of the most serious factors affecting the transportation industry. In an effort to minimize its impact, a German research institute and the manufacturers of Mercedes-Benz joined forces to investigate the corrosion occurring in automotive rivets and sheet metal. Using COMSOL Multiphysics simulation, they were able to study corrosion’s effects on car components.
Sensing the Bio in Biosensor Design with a Simulation App
Biosensors are the workhorses of the analytical tools used for detailed mechanistic understanding at the molecular level of biological systems. The applications of these analysis tools are countless for the detection of biomolecules in the pharmaceutical, health care, and food industries; agriculture; environmental technologies; and in general for research of biological systems. The biosensor demo app is a good example of an application where non-experts can benefit from accurate multiphysics simulations.
An Analysis of Syngas Combustion in a Round-Jet Burner
In this blog post, we investigate syngas combustion in a round-jet burner using the Reacting Flow interface and the Heat Transfer in Solids interface. The results from this benchmark model are compared to experimental findings.
Using Simulation to Optimize Biopharmaceutical Processes
The biological and chemical processes behind the development of biopharmaceuticals have an important effect on product quality. With its ability to deliver quick results at a lower cost, simulation is a valuable resource in studying and optimizing these techniques. Learn how COMSOL Multiphysics can benefit your modeling of biopharmaceutical processes.
Simulating an Ideal Stirred Tank Reactor System
Continuous stirred tank reactors (CSTRs), or ideal stirred tank reactors, are frequently used in the chemical and biochemical industries. This reactor type operates at steady state and because of its good mixing properties, it is assumed that the composition throughout the reactor is uniform. Using a new model in the Reaction Engineering interface, we can visualize the dynamics within an ideal system of tank reactors.
New and Revamped Chemical Engineering Interfaces
Many exciting features for chemical engineering modeling were introduced in COMSOL Multiphysics version 5.0. In this blog post, I will discuss the most important updates. There are some new modeling interfaces, such as the Chemistry interface, and some that have been revamped and improved, like the Reaction Engineering interface. To begin with, I will recap the modeling interfaces for reaction engineering and mass transport.
