The model simulates non-premixed turbulent combustion of syngas (synthesis gas) in a simple round-jet burner. Syngas is a gas mixture, primarily composed of hydrogen, carbon monoxide and carbon dioxide. The name syngas relates to its use in creating synthetic natural gas. In the model, ... En savoir plus
This example models wicking in a porous medium. Wicking is the phenomenon that occurs when a dry porous material is put into contact with a fluid: it will absorb the fluid due to capillary forces. The absorption will continue until an equilibrium is reached where the gravitational forces ... En savoir plus
This example is a benchmark problem for simulating phase change in porous media. It studies the melting process of an ice inclusion within porous media and therefore demonstrates how to couple Darcy's Law with the Heat Transfer in Porous Media interface including phase change. En savoir plus
This example shows how the mixing capability of a stirred vessel can be evaluated. To efficiently reach the steady operational conditions the turbulent flow is solved for using a frozen rotor analysis, and a following time dependent simulation. When a quasi-steady flow field has ... En savoir plus
In this benchmark model for blood flow in a centrifugal pump, simulations are performed for several flow rates and pump speeds. The modeled geometry is taken from the FDA’s Computational Round Robin and the results are in good agreement with the experimental data. The computed shear ... En savoir plus
This tutorial model illustrates how to analyze the thermal effects of the sun as an external radiative source and considers wavelength-dependent surface emissivities. Specifically, the model features two coolers containing beverage cans that are exposed to ambient conditions and a beach ... En savoir plus
We present the results from a comparison of the level set, phase field, and moving mesh methods for modeling free liquid surfaces in the COMSOL Multiphysics® software. The comparison is carried out using an example problem. The example studies the formation of surface waves ... En savoir plus
This benchmark models two-phase flow in a porous medium in 1D, where the flow can be analytically described by the Buckley-Leverett equation. En savoir plus
Marangoni convection occurs when the surface tension of an interface (generally liquid-air) depends on the concentration of a species or on the temperature distribution. In the case of temperature dependence, the Marangoni effect is also called thermo-capillary convection. The Marangoni ... 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
