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.
Improving Architectural Designs with Building Physics Simulation
Building physics simulation can help engineers develop more energy-efficient architectural designs. We talked to Built Environments, Inc. to get a few examples of how.
How to Model Sparging in COMSOL Multiphysics®
Sparging, the process of bubbling a gas into a liquid, is seen most notably in carbonation, such as for soda and seltzer water. This mass transfer process can be modeled in COMSOL Multiphysics®.
How to Place Inlet and Outlet Boundary Conditions in CFD Simulations
When setting up fluid flow simulations, at what distance can we apply boundary conditions without interfering with the process? Here, we discuss how to place inlet and outlet boundary conditions.
Describing Viscoelastic Behavior with an Oldroyd-B Benchmark
The Oldroyd-B model is used to define viscoelastic behavior in fluids such as clay, toothpaste, and oil. We present a benchmark model for a fluid with viscoelastic behavior under strain.
CFD Benchmark: Examining Fluid Flow in a Transonic Diffuser
You can analyze the fluid flow in a transonic diffuser using CFD simulation. Get details in this blog post featuring a benchmark model based on research by M. Sajben et al.
How to Analyze a Glacier via Gradient-Based Optimization
This post highlights a gradient-based optimization method that geophysical engineers can use to analyze, for instance, the movement and sensitivity of a glacier.
Modeling a Tubular Reactor for Optimized Polymer Manufacturing
Chemical engineers can model tubular reactors to optimize them for specific manufacturing and production processes, such as for the polymerization of polyester, as this example shows.
