This model illustrates the greenhouse effect in a box covered by a plate and exposed to sun radiation over a day. The temperature variation is monitored in two cases: with a plate made of glass, transparent in the solar spectral band and opaque for the ambient solar band with a fully ... En savoir plus
AT cut quartz crystals are widely employed in a range of applications, from oscillators to microbalances. One of the important properties of the AT cut is that the resonant frequency of the crystal is temperature independent to first order. This is desirable in both mass sensing and ... En savoir plus
Many piezoelectric materials are ferroelectric. Ferroelectric materials exhibit nonlinear polarization behavior, such as hysteresis and saturation at large applied electric fields. In addition, the polarization and mechanical deformations in such materials can be strongly coupled due to ... En savoir plus
This model shows how to model an electrolyte-gated organic field-effect transistor based on a general drift-diffusion model. The model uses the Stabilized Convection-Diffusion Equation interface and the Electrostatics interface. The transistor characteristics are visualized. Formation of ... En savoir plus
The incompressible boundary layer on a flat plate in the absence of a pressure gradient is usually referred to as the Blasius boundary layer. The steady, laminar boundary layer developing downstream of the leading edge eventually becomes unstable to Tollmien-Schlichting waves and finally ... En savoir plus
This model simulates an electrodeless lamp with argon/mercury chemistry. The low excitation threshold for mercury atoms means that even though the mercury is present in small concentrations, its behavior dominates. There is strong UV emission from the plasma at 185 nm and 253 nm. The UV ... En savoir plus
This tutorial model presents a study showing the transient negative mobility and the negative differential conductivity effects in xenon. The stationary and time dependent Boltzmann equation in the two-term approximation is used to compute the electron energy distribution function. ... En savoir plus
This tutorial shows how to simulate coupled heat and moisture transport in a wall. The wall is modeled considering an air flow between interior and exterior varying with time. The 1D model is the third benchmark test defined in HAMSTAD-WP2 Modeling for the validation of numerical ... En savoir plus
This app demonstrates the usage of a surrogate model function for predicting the cell voltage, cell open circuit voltage and internal resistance of an NMC111/graphite battery cell undergoing a battery test cycle. The surrogate function, a Deep Neural Network, has been fitted to a ... En savoir plus
In this example of a peristaltic pump, rollers squeeze a flexible tube and the compression drives a fluid through the tube. The model demonstrates how to use the Fluid-Structure Interaction interface. The main advantage of the peristaltic pump is that no seals, valves or other internal ... En savoir plus
