Maintaining Cold Temperatures in an Isothermal Box with Simulation
Heat transfer modeling is more accurate when you can input historical climate data from ASHRAE, such as in this example of an isothermal box designed to transport perishable items and medicine.
Evaluating a Fire-Resistant Overpack for Nuclear Waste
Confinement system overpacks are used to safely store radioactive waste. Sogin uses heat transfer modeling to design safe and reliable overpacks that are resistant to fire.
Keynote Video: Simulating the Drying of Cellular Foods
How about them (dried) apples? Empa uses multiscale modeling to analyze the dehydration of soft cellular food products, such as dried fruit, and scale their processes for mass production.
Simulating Multiphase Flow in Porous Media with a Low Permeable Lens
Modeling phase transport helps you study the multiphase flow through a porous medium (such as groundwater through soil).
Studying Shock Wave Phenomena with a Shock Tube Application
Shock waves used to be a theoretical problem only. Then, shock tubes enabled experimentation, but it was costly and inefficient. Enter numerical modeling applications.
Keynote Video: Designing Improved Heart Pumps with Simulation
Abbott Laboratories designed “the most complex machine ever implanted into a human being” — an LVAD for heart failure patients — using multiphysics modeling. The result? Saved lives.
FEM vs. FVM
Finite element methods, finite volume methods, or a hybrid approach: Which is the best choice for CFD? It depends on the fluid flow problem you’re trying to solve.
Using Discontinuous Meshes for Conjugate Heat Transfer Modeling
You can use different discontinuous meshes in neighboring domains in COMSOL Multiphysics®. This capability comes in handy, particularly when modeling conjugate heat transfer problems.
