The study explores charge transport dynamics in polyethylene, a common solid dielectric insulation material. It employs a bipolar charge transport model to calculate the densities of electrons, holes, and their trapped counterparts. The simulation's outcomes for discharge current and ... Mehr lesen
In this model of an ammonia-fed solid oxide fuel cell, the required hydrogen is supplied through endothermic thermal decomposition of ammonia. The model includes the full coupling between the mass balances and gas flow in the H2 and O2 gas diffusion electrodes, the momentum balances in ... Mehr lesen
This tutorial model shows how to model car cabin acoustics using a hybrid FEM-ray approach. The particular example is that of a tweeter located in the dashboard of the car near the windscreen. A FEM based sub-model of the speaker and its immediate surroundings is used to compute a ... Mehr lesen
This model utilizes a continuation solver to efficiently compute the current–voltage characteristics of a corona discharge generated by a wire-to-wire configuration. It provides a flexible framework that can be easily adapted to study other discharge configurations and types. Mehr lesen
Diaphragm accumulators are essential components that store energy and regulate hydraulic systems. A flexible rubber diaphragm divides the hydraulic fluid from a compressible inert gas, typically nitrogen. These accumulators perform multiple tasks, such as temporarily storing hydraulic ...
