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 […]

Fluid-Structure Interaction (FSI) using COMSOL Multiphysics

September 6, 2013

Today we have the pleasure of welcoming Nagi Elabbasi of Veryst Engineering as a guest blogger. Read on to see what this COMSOL Certified Consultant has to say about fluid-structure interaction. Two weeks ago I led a webinar on fluid-structure interaction (FSI) using COMSOL Multiphysics. FSI involves coupling between a deformable or moving structure and a surrounding or internal fluid flow. There is a growing number of engineering and scientific problems where a purely structural or purely CFD analysis just […]
