This tutorial model solves the incompressible Navier-Stokes equations in a backstep geometry using the Laminar Flow interface. A characteristic feature of fluid flow in geometries of this kind is the recirculation region that forms where the flow exits the narrow inlet region. The model ... Mehr lesen
Cyclones are used in a variety of applications ranging from the mining industry to vacuum cleaners. The flow in a cyclone is characterized by a very strong swirl, which makes it difficult to simulate. In this tutorial example, the v2-f turbulence model is used to simulate the flow in a ...

Maximizing product yield is a main task in chemical reaction engineering. This can be especially challenging if the desired product, once formed, can be consumed by further reactions. This example investigates such a series reaction as it occurs in a tubular reactor. You will start by ... Mehr lesen
Topology optimization of the Navier-Stokes equations is encountered in different branches and applications, such as in the design of ventilation systems for cars. A common technique applicable to such problems is to let the distribution of porous material vary continuously. In this ... Mehr lesen
The S-N curve, also called the Wöhler curve, is one of the most popular methods for fatigue evaluation. The curve relates stress amplitude to the limiting fatigue life and can be obtained directly from a set of standard fatigue test. Many times our applications are subjected to ... 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
Diese App für einen Rohrreaktor und das dazugehörige eingebettete Modell zeigt, wie die Rechengeschwindigkeit durch die Verwendung eines Ersatzmodells im Gegensatz zu einem vollwertigen Finite-Elemente-Modell erhöht werden kann. Ein Ersatzmodell ist ein einfacheres, in der Regel ... Mehr lesen
The Marangoni effect results in a slip velocity in the tangential direction on a fluid/fluid interface due to gradients in the surface tension coefficient. When the surface tension coefficient is constant, a two-fluid system may exist in static equilibrium. This is because the surface ... Mehr lesen
In an alkaline electrolyzer stack, all cells share the same electrolyte. As a result of all cells being in ionic contact, parasitic shunt currents flow between the cells through the manifolds and the electrolyte channels, on both the inlet and outlet side. This example models a ... Mehr lesen
This example illustrates the modeling of a multibody mechanism submerged in fluid. The mechanism considered here consists of two fins connected to a central rigid body through hinge joints. A transient fluid-structure interaction problem is solved to simulate the swimming behavior where ... Mehr lesen
