This benchmark model computes the transient pressure distribution and film height in a squeeze film bearing for lubrication in a nonconformal conjunction of a solid sphere and an elastic wall separated by a lubricant film. This model solves the benchmark case of hydrodynamic interaction ... En savoir plus
This tutorial example simulates the flow in a flat bottom mixer containing, agitated by a pitched four blade impeller, where the fluid is water, and flow is assumed to be turbulent. The flow in the mixer is modeled using the k-ε turbulence model, and a time-dependent simulation ... En savoir plus
This example demonstrates how to model phase transition by a moving boundary interface according to the Stefan problem. A square cavity containing both solid and liquid tin is submitted to a temperature difference between left and right boundaries. Fluid and solid parts are solved in ... En savoir plus
This model shows how to use simulations to predict power numbers with Power Law fluids in a mixer. It simulates the behavior of flow in a flat bottom tank with a single four-blade pitched impeller. The flow was modeled as laminar and the frozen rotor approach was used to solve the ... En savoir plus
The level set method is well suited for problems with moving boundaries in which the geometry’s topology changes with time. A bubble of oil that travels up through water and finally merges with oil at the top causes this kind of topology change. For problems where the topology is ... En savoir plus
When a temperature gradient in a gas exists, suspended particles will tend to move from regions of high temperature to low. The force which produces this effect is called the thermophoretic force. Gas molecules colliding with a particle from the hot side have a higher velocity than the ... En savoir plus
This example shows how to compute thermally induced stresses in a turbine stator blade using the Thermal Stress, Solid interface. The conditions within gas turbines are extreme. The pressure can be as high as 40 bar, and the temperature more than 1000 K. Any new component must therefore ... En savoir plus
This model demonstrates the use of the Two-Phase Thin-Film Flow, Phase Field multiphysics coupling, which can be used to predict the evolution of an interface between two different, immiscible fluids in thin, narrow channels. The example here presents a free boundary lubrication ... En savoir plus
This example extends the analysis made in the model Electrodeposition on a Resistive Patterned Wafer by including the diffusion and convection of copper ions in the electrolyte. The coupled mass transport convection-diffusion effects are of interest in this type of reactor since they ... En savoir plus
This model of a two-story house can be used to examine a contaminant leak and the subsequent contaminant dispersion that occurs due to convection and diffusion. Airflow and recirculation within the home are dependent on vent placement, and flow velocity may also vary at each vent. ... En savoir plus
