Viscosity Ramping Improves the Convergence of CFD Models
Viscosity ramping can help decrease the computation time for your models by solving for higher viscosities and using the solutions as initial conditions for the problem at lower viscosities.
Model How the Bubbles in a Glass of Stout Beer Sink, Not Rise
Ever notice how the bubbles in certain kinds of stout beer sink to the bottom of the glass instead of rising to the top? We explain this phenomenon using fluid flow simulation.
App: Design a Geothermal Heat Pump’s Heat Recovery System
The design and installation of a geothermal heat pump often involves many different configurations, which can be easily tested with a simulation app. See an example in action here.
Improving Vascular Access for the Treatment of ESRD Patients
By combining CFD simulations with shape optimization techniques, biomedical engineers can better understand and predict vascular access for renal disease treatments.
Free Surface Computations in Mixers and Rotating Machinery
Learn different approaches for performing free surface computations in mixers and rotating machinery using COMSOL Multiphysics® and the add-on CFD Module and Mixer Module.
Optimize NACA Airfoil Designs with a Simulation App
You can design a simulation app to accurately compute lift and drag forces and optimize any airfoil following the NACA naming convention. Learn more and see an example demo app.
Studying the Swimming Patterns of Fish with Simulation
Researchers from the Università Roma Tre used simulation to study the carangiform swimming pattern of certain fish, the dynamics of which can be used to design aquatic vehicles and robots.
Simulate Three-Phase Flow with a New Phase Field Interface
The Three-Phase Flow, Phase Field interface, used for modeling separated three-phase flow, computes the shape of the interfaces between the 3 phases and accounts for interactions with walls.
