The aerodynamic properties of a wing, propeller, or turbine blade are to a large extent determined by the precise shape of the airfoil that is used. The NACA Airfoil Optimization application computes the two main aerodynamic properties (the lift and drag coefficients) of a fully ... En savoir plus
For more than 50 years, it has been known that neutrally buoyant particles in a flow channel tend to converge to specific locations in the channel cross section. For a cylindrical pipe, or two parallel planes carrying a Poiseuille flow, the equilibrium position is about 0.6 times the ... En savoir plus
This example demonstrates how to compute transmission line parameters such as series resistance, series inductance, shunt conductance, and shunt capacitance per unit length using the predefined Transmission Line RLGC Parameters multiphysics interface. The demonstration also includes the ... En savoir plus
The impressed current cathodic protection (ICCP) system is often employed to mitigate corrosion of buried pipelines in the oil and gas industry. Metallic objects such as buried pipelines, which are present within the current flow of the ICCP system, may suffer from the stray current ... En savoir plus
This model simulates the coupling of free-space laser radiation into waveguide modes using an optical grating coupler. The coupling efficiency and the radiation loss are calculated for different angles of incidence of the laser beam. En savoir plus
UHF RFID tags are widely used for identifying and tracking animals. This model simulates a passive radio-frequency identification (RFID) tag for the UHF frequency range. With respect to the chip transponder’s complex impedance, a reflection coefficient is computed. This is done using an ... En savoir plus
A Fresnel rhomb is a prism that uses total internal reflection to manipulate the polarization of light. In this example, light in the prism is internally reflected at an angle of incidence that induces a 45-degree phase delay between s- and p-polarized radiation. By subjecting the light ...

FEM simulation can be used to obtain a SAW velocity and some related parameters (squared electromechanical coupling coefficient, reflectivity, etc.) for different typical configurations. Such parameters are input data for various analytical and semi-analytical methods of SAW device ... En savoir plus
This model studies the temperature effects on the viscoelastic stress relaxation in a long thick-walled cylinder. In particular, decay of the stresses under the influence of the temperature field during a period of two hours is studied. A four-term generalized Maxwell model represents ... En savoir plus
Crystallization is a key separation process in e.g. pharmaceuticals production. It is the process by which a chemical species is separated from solution by forming a crystal. To achieve the required product properties, control over the crystal particle size distribution is necessary. ... En savoir plus
