This model computes the particle flux, number density and pressure on the surface of a plate that rotates in a highly directional molecular flow. The results obtained are compared with those from other, approximate, techniques for computing molecular flows. Mehr lesen
Ein Tonpilz-Schallwandler wird für relativ niederfrequente Schallabstrahlung mit hoher Leistung verwendet. Er ist eine der beliebtesten Schallwandler-Konfigurationen für SONAR-Anwendungen. Der Schwinger besteht aus piezokeramischen Ringen, die zwischen einer Kopfmasse und einer Endmasse ... Mehr lesen
This model shows how you can implement a user defined hyperelastic material, using the strain density energy function. The model used is a general Mooney–Rivlin hyperelastic material model defined by a polynomial. In this example, you will see two material models based on the defined ... Mehr lesen
This model demonstrates an integrated structural-thermal-optical performance (STOP) analysis of an optical system. The Petzval Lens tutoral is used as the basis for this model, together with a simple barrel geometry The isothermal model performs a Parametric Sweep over several uniform ... Mehr lesen
Plate reactors running under continuous conditions have emerged as candidates to replace batch reactors, primarily in fine chemicals and pharmaceuticals production. One of the advantages of the plate reactor design is that it allows for efficient temperature control of the reacting ... Mehr lesen
This example was originally formulated by Albert Witarsa under Professor Bruce Finlayson’s supervision at the University of Washington in Seattle. It was part of a graduate course in which the assignment consisted of evaluating the potential of patents in the field of microfluidics ... Mehr lesen
This model simulates atmospheric galvanic corrosion of an aluminum alloy in contact with steel. The electrolyte film thickness depends on the relative humidity of the surrounding air and the salt load density of NaCl crystals on the metal surface. Empirical expressions for the oxygen ... Mehr lesen
This model incorporates the transport and electrolytic reaction in the treatment of tumor tissue. Oxygen evolution at the anode produces protons, which lowers the pH, while chlorine production also leads to lowered pH through the hydrolysis of chlorine. One effect of a low pH is the ... Mehr lesen
With an increase in the parallel component of the applied field, carriers can gain energies above the ambient thermal energy and be able to transfer energy gained by the field to the lattice by optical phonon emission. The latter effect leads to a saturation of the carriers mobility. The ... Mehr lesen
This 2D axisymmetric model demonstrates the operation of a pyroelectric detector found in instruments for measuring laser energy. A disk of lithium niobate (LiNbO3) is sandwiched between two electrodes and connected to an external circuit. The disk is mounted on a ring-shaped ... Mehr lesen
