Wir präsentieren die Ergebnisse eines Vergleichs der Level-Set-, Phasenfeld- und Moving-Mesh-Methoden zur Modellierung freier Flüssigkeitsoberflächen in der Software COMSOL Multiphysics®. Der Vergleich wird anhand eines Beispielproblems durchgeführt. Das Beispiel untersucht die Bildung ... Mehr lesen
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 ... Mehr lesen
This example is about the modeling of the fiber drawing process. Thermal fiber drawing is a process in which a comparatively thicker structure is heated and drawn into extended lengths of microstructured fiber. This process is done by passing them through the furnace and pulling them ... Mehr lesen
This example illustrates multiphase flow modeling in an airlift loop reactor. The reactor is filled with water and air bubbles are injected at the bottom through two frits. Due to buoyancy, the bubbles rise, inducing a circulating motion of the liquid. The model specifically investigates ... Mehr lesen
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 ... Mehr lesen
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. Mehr lesen
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 ... Mehr lesen
This model studies a part of a shell-and-tube heat exchanger where hot water enters from above. The cooling medium flows through the tubes that, in this model, impose a constant temperature at the walls. Furthermore, the tubes are assumed to be made of stainless steel and the heat flux ...

This example demonstrates simulation of a turbulent flow in a geometry with an air filter. Porous material of the filter induces an abrupt pressure drop and drastic increase of turbulence level inside the filter. Mehr lesen
This model exemplifies the use of the Rotating Machinery interface, which allows you to model moving rotating parts in, for example, stirred tanks, mixers, and pumps. The Rotating Machinery interface formulates the Navier-Stokes equations in a rotating coordinate system. Parts that are ... Mehr lesen
