Modeling Fermentation in Beer Brewing Yields a Better Product

Bridget Cunningham | April 25, 2016

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.

We previously wrote about how engineers at IAV, a leading automotive engineering company, used simulation to reduce sloshing in vehicles. Today, we’ll demonstrate how to set up your own sloshing tank model in COMSOL Multiphysics using a separated two-phase flow model with two fluids that have a large difference in density.

Inductive devices exhibit a range of electromagnetic effects that have to be taken into account when they are utilized as part of any application. With the tools provided by the AC/DC Module in COMSOL Multiphysics, you can model and design an inductor in a straightforward yet accurate way, as well as calculate the device characteristics your application demands.

We’ve learned how to simulate a simple bit-by-bit holographic data storage model in COMSOL Multiphysics by choosing an appropriate beam size and implementing the recording and retrieval process. Today, we step forward and demonstrate how to simulate a more difficult and complex, yet more realistic and interesting model of a holographic page data storage system.

We can solve many of the world’s energy sustainability problems by harnessing the power of the sun through fusion energy. Tokamaks are devices that test the practicality of employing fusion energy on Earth. ITER, which will be the largest tokamak on Earth when complete, has required years of research and a magnitude of resources. Using COMSOL Multiphysics, a group of researchers investigated whether the tritium breeding modules (TBMs) in ITER produce magnetic perturbation that could generate unacceptable plasma losses.

When it comes to creating the next generation of flat panel displays and solid-state area lighting, organic light-emitting diodes, or OLEDs, may be used to help. While recognized for its various advantages, this emerging technology suffers from some weaknesses that reduce its overall efficiency. One such example is light loss, which is partially caused by the plasmon coupling effect. Looking to reduce the effect’s prominence in OLED devices, researchers from Konica Minolta Laboratory turned to the COMSOL Multiphysics® software.

We’ve talked a lot on the blog about the different types of simulation apps that you can build. But did you know that you can create an app that plays sounds? The Organ Pipe Designer allows users to investigate the parameters behind an organ pipe configuration and then play the resulting sounds to really see — and hear — a design in action. Let’s learn more about the physics behind our underlying model and its transformation into an easy-to-use app.

Removing bacteria and contaminants from water is an important point of concern for safety reasons. One method of purification involves the use of water treatment basins. CFD modeling provides an efficient route for optimizing the design of these basins to ensure their overall effectiveness. Simulation apps, as we’ll highlight here, are taking things one step further by extending the scope of such modeling capabilities to a much wider audience.

The Newman model and its variants form the standard theory used to successfully predict the behavior of lithium-ion battery design under a range of operating conditions. In the Newman model, the geometry of the porous structure of the battery electrodes is not described in detail; instead, typical averaged dimensions are used as input to describe the electrodes as homogeneous and isotropic materials. But how accurate is this approach compared to a detailed, heterogeneous geometric model? Let’s find out.

Radiators, refrigerators, and geothermal pumps all need to efficiently extract heat from one fluid to another without mixing them. Among all of the different heat exchanger designs, finned pipes aim to increase the exchange surface between the content of a pipe and the exterior using fins. Finned pipes usually show a geometrical periodicity along the length, which we will take advantage of in this demo app to reduce computational costs.

Have you ever wanted to write out mesh and analysis data from COMSOL Multiphysics into a text file? You may want to do this when passing information to another software program or even just into a spreadsheet. You often want to customize the exact format in which such data is written, depending upon the needs of the other tools with which you are working. This is very easy to do with the Application Builder. Let’s find out how!
