Buoyancy-Driven μPCR for DNA Amplification
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.
Modeling PSU Cooling with COMSOL
A forced convection cooling system, such as a PSU, is used for removing excess heat produced by electrical computer components. You can model this device in COMSOL Multiphysics®.
Solving Algebraic Field Equations
COMSOL Multiphysics® is commonly used to solve PDEs, ODEs, and initial value problems. However, did you know that you can also solve algebraic and even transcendental equations?
Simulating Viscous Fingering Using Equation-Based Modeling
A prospective user of COMSOL approached me about modeling viscous fingering, which is an effect seen in porous media flow. He hadn’t found a satisfying solution elsewhere, so he turned to COMSOL. I’d like to share with you some of my insight on how to go from idea to model to simulation by taking a “do-it-yourself approach” and utilizing the equation-based modeling capabilities of COMSOL Multiphysics.
COMSOL Multiphysics Version 4.4 Released Today
You’ve seen glimpses of our new software release at the COMSOL Conference and perhaps engaged in commentary around it in social media. Today marks the official release of COMSOL Multiphysics version 4.4, and you can now learn about the software updates in detail and download it if you are on subscription.
Simulating Thermal Stress in a Turbine Stator Blade
We can leverage simulation software to understand and optimize component design. Every simulation relies on a model that is a representation of the reality that the application finds itself in. Modeling enables us to represent this reality with enough detail to receive relevant information about the particular application or component. Let’s have a look at a thermal stress analysis of the turbine stator blade model from our Model Gallery and investigate the effects of heat transfer and thermal stress that […]
How to Model a Shell and Tube Heat Exchanger
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
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 […]
