Predicting Cavitation in Journal Bearings
Journal bearings are lubricated components that support a rotating shaft. Cavitation affects the performance of these bearings and must be considered during the design stage. Here, I’ll explain what journal bearings are and why predicting cavitation is important, as well as share an industry example with you.
Which Multiphase Flow Interface Should I Use?
If you are interested in using COMSOL Multiphysics software to solve multiphase flow problems, you may be wondering which multiphase flow interface to choose. This is your guide to the six interface options available to you and when you should use them.
How can you use an electric field to control the movement of electrically neutral particles? This may sound impossible, but in this blog entry, we will see that the phenomenon of dielectrophoresis (DEP) can do the trick. We will learn how DEP can be applied to particle separation and demonstrate a very easy-to-use biomedical simulation app that is created with the Application Builder and run with COMSOL Server™.
Visualizing Fluid Flow with Streamline Plots
Last month, we saw examples of contour plots (and their 3D counterparts, isosurfaces) that were created to show the stress in a pulley and the acoustic frequency in a loudspeaker. In this installment of the postprocessing series, we’ll explore the use of streamlines to visually describe fluid flow.
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.
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.
