How to Easily Connect 1D Pipes to 3D Flow Domains
In earlier versions of COMSOL Multiphysics, it was cumbersome to connect 1D pipes to 3D flow domains. However, did you know that a new feature in COMSOL Multiphysics version 5.0 now allows you to easily accomplish this? Let me demonstrate how this feature works.
Hydrocooling Analysis for Fresh Produce Safety
Worried about bacteria in your tomatoes? Research presented at the COMSOL Conference 2014 Boston shows where bacteria seeps through during hydrocooling — and how we can avoid ingesting it.
Improving the Beer Brewing Process with Simulation
There are two aspects of home brewing: the culinary side and the engineering one. Many beer lovers start brewing either to improve a recipe, try to clone their favorite beer, or even simply just to see how it works. After brewing a few batches, however, it turns out that the brewing process can also be very challenging from an engineering point of view.
Optimizing the Continuous Casting Process with Simulation
The Swiss steel company SMS Concast has been leveraging multiphysics simulation to optimize the steelmaking process of continuous casting. Through research conducted using COMSOL Multiphysics, the R&D team at SMS Concast was able to implement a new technique that allowed a steelmaking plant in Taiwan to reduce yearly CO2 emissions by about 40,000 tons.
Understanding Traffic Congestion via Equation-Based Modeling
We have all experienced the boredom and frustration of being stuck in a traffic jam. Very often, traffic congestion comes and goes for no obvious reason. Employing the analogy to gas dynamics, we can now simulate traffic flow using the equation-based modeling capabilities of COMSOL Multiphysics and gain a better understanding of why congestion happens.
The Physics Behind Baseball Pitches
Professional baseball pitchers are able to make a baseball move left, right, down, and even up (sort of) to get it by the opposing batter. The physics behind this can be explained by the Magnus effect.
Acoustic Levitation Puts a Pure Spin on Medicine Fabrication
The need for a contaminant-free space to manufacture medicine has led scientists to try many creative new approaches to improve the process. At Argonne National Lab, creating a device that floats and rotates chemical compounds in thin air was just the answer they were looking for. It meant two important changes: the amount of each chemical necessary could be implemented very precisely and the risk of outside impurities disrupting the results was minimized.
Seas of Change for Wind Turbines
Wind turbine noise is a (hotly disputed) topic that we’ve mentioned on the blog before. While research into noise production by wind farms is still being debated among researchers, one way we’ve found to overcome these noisy turbine troubles is to place turbines offshore where they can’t be heard and, conveniently, high winds with more regularity make energy production more effective. However, a question that comes to mind is: What impact do offshore wind farms have on marine life?
