Journal Bearing with Cavitation
A journal bearing is composed of an outer cylinder (bearing) wrapped around an inner rotating journal (shaft), with a lubricant separating the two. Under certain operating conditions, cavitation can occur between the bearing and the journal, leading to component damage and failure. ... En savoir plus
Spray Particle Deposition in Human Airways nouveau
This example demonstrates how to import and repair a surface mesh from an STL file, and to create a mesh to simulate nasal spray application inside the human upper airways. It further demonstrates how to combine the repaired mesh with the geometry of a nasal spray, then to remesh and ... En savoir plus
Modeling a Sphere Falling on a Water Surface
This model shows modeling of a sphere falling on a water surface. Specifically, it models the oscillating motion of a buoyant sphere as it falls through air and interacts with the air-water interface to finally float on water. Get more details in our blog post: Modeling a Sphere Falling ... En savoir plus
Opto-Acoustophoretic Effect in an Acoustofluidic Trap
Opto-acoustophoresis is a term used to describe the interplay between acoustics and optical fields. In most cases (including this) the optical field is heating up the material and therefore affecting the acoustic field. In this example of an acoustic trap a set of particle are trapped ...

Using Assembly Meshing for Conjugate Heat Transfer Modeling
You can use assembly meshing to reduce the number of mesh elements in your model, which is especially useful for conjugate heat transfer simulation in cases where the fluid domains can be handled with swept mesh. These models demonstrate how to use form assembly and discontinuous meshes ... En savoir plus
Rayleigh-Benard
Rayleigh-Bénard's convection cells is a classic in fluid dynamics. We present here two different approaches for computing the critical Rayleigh number above which the cells form. En savoir plus
Turbulent Parallel Flow in a Channel with Adjacent Fluid and Porous Regions
This setup demonstrates how the characteristics of turbulent flow in a channel are modified by the presence of an adjacent porous region. Asymmetric velocity profiles, higher turbulence levels, and higher friction coefficients both at the solid wall and the fluid-porous interface are ... En savoir plus
Flow Through a Uniform Inclined Screen
This model simulates the flow through a uniform inclined screen using the Screen feature in Single-Phase Flow physics and compares the results with an analytic solution. En savoir plus
Carbonation in Water
This example shows how to model carbonation, which is a type of sparging. Sparging is a mass transfer process between a gas and a liquid that is common in industry (such as beverage carbonation and photobioreactor applications) and at home (aquarium aeration). In the carbonation model, ... En savoir plus
1D Plane Slider Bearing
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic slider bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. En savoir plus
