The induced currents in a copper cylinder produce heat, and when the temperature rises, the electrical conductivity of the copper changes. The heating caused by the induced currents is called inductive heating. Generally heating due to...
This example studies the steady flow of an ideal gas in porous media, where variations in gas density are taken into account through Equation-based Modeling. Darcy’s law describes the velocity vector in the porous structure and the...
This model exemplifies the coupling between flow of a gas in an open channel and in a porous catalyst attached to one of the channel walls. The flow is described by the Navier-Stokes equation in the free region, and using the Brinkman...
The Non-Newtonian Flow application mode is suitable for flows where viscosity variations arise due to a fluid’s shear rate. The application mode is almost identical to the Incompressible Navier-Stokes application mode, except that...
The model in this study deals with a micro heat exchanger made of stainless steel. These types of heat exchangers are found in lab-on-a-chip devices in biotechnology and in micro reactors, for example for micro fuel cells. A square...
In this example, we study the diffusion of a chemical species through a membrane. The system is used to measure the permeability of gases in membranes. The permeability of the membrane is measured by introducing the species of...
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...
This example shows a plane stress analysis of a mechanical component. The component is cut from a 4 mm steel plate. The thickness is small compared to the length and breadth in the x-y plane. Due to this, and the fact that the applied...
A tube connection consisting of a flange with four pre-stressed bolts is subjected to tensile forces. In order to compute the influence of the tensile force on the stress level in the bolt, a parametric analysis is done. Because of...
The rotor in an electric motor is analyzed. In the design of a motor it is important that no eigenfrequencies for the rotor lie within the operating interval of the revolution speed (in revolutions / second) for the motor. If the...
