Characterizing the Flow and Choosing the Right Interface

April 7, 2014

No matter the focus of your modeling project, you have probably had to consider fluid flow at some point. Here, we discuss how to characterize the flow and choose the correct CFD interface.

Simulating Kelvin-Helmholtz Instability and Climate Dynamics

March 18, 2014

Q: What do heated soap bubbles, wavy clouds, and Jupiter’s Great Red Spot have in common? A. An unstable motion called Kelvin-Helmholtz instability.

Buoyancy-Driven μPCR for DNA Amplification

February 26, 2014

True crime + simulation: The more DNA in a sample, the easier it is to accurately test and identify biomolecules, cells, and even an entire person during forensic investigations.

Improving Bioreactor Performance with COMSOL Multiphysics

January 31, 2014

A guest blogger from Continuum Blue gives an overview of what the consultancy can do using simulation for their biomedical engineering clients.

Modeling a Displacement Ventilation System

January 27, 2014

There are 2 different types of ventilation systems: mixing ventilation and displacement ventilation. Displacement ventilation is mainly found in offices, schools, and other public spaces.

Optimizing Dialyzer Design Using Multiphysics Simulation

December 19, 2013

A while back, I had the opportunity to speak with Steven Conrad, a critical care physician at the Louisiana State University (LSU) Health Science Center in New Orleans. Not only is Dr. Conrad a physician as well as a professor at LSU, he’s also a biomedical engineer who uses finite element analysis (FEA) to conduct research on the design of dialyzers. Dr. Conrad uses COMSOL Multiphysics to gain a deeper understanding of the physics behind these devices, and to create […]

Starting Small with Sonar Dome Design

September 13, 2013

Starting the design process by testing on a small scale is often the best way to tackle issues affecting large objects, like a ship. Detailed in COMSOL News 2013, researchers at INSEAN, The Italian Ship Model Basin, used small-scale testing and then simulation to analyze the effect of placing a sonar system within the bulbous bow at the hull of a ship. Using a small-scale model of a bulbous bow, the researchers at INSEAN performed fluid-structure interaction experiments, and subsequently […]

How to Model a Shell and Tube Heat Exchanger

September 11, 2013

Shell and tube heat exchangers are one of the most widely used type of heat exchanger in the processing industries (65% of the market according to H. S. Lee’s book, Thermal Design) and are commonly found in oil refineries, nuclear power plants, and other large-scale chemical processes. Additionally, they can be found in many engines and are used to cool hydraulic fluid and oil. There are a variety of different configurations for these heat exchangers, but their basic concept can […]
