A gearbox used in a vacuum cleaner robot is evaluated regarding noise and vibration in COMSOL Multiphysics®, using the Multibody Dynamics and the Acoustics Module. The real gearbox is powered by a DC motor and consists of four plastic helical gears forming a gear train and is used to ... En savoir plus
Calorimetry is the method of choice for determining one of the most elementary physical quantities: heat, Q [in J]. Depending on the individual issue a wide range of techniques, devices and methods are available for users [1]. One approach is called isothermal microcalorimetry (IMC). It ... En savoir plus
High temperature and pressure alkaline electrolysis is an innovative and promising technology for water electrolysis for hydrogen production. Introducing simulation at early stage development allows to study the effect of the microstructure parameters on performance and guide the ... En savoir plus
The present work introduces a new methodology, based on COMSOL Multiphysics® Application Builder, to account for the “beam trapping” effect in multiphysical modelling of laser welding. Incident intensities involved in laser welding processes are high enough to induce material ... En savoir plus
In this numerical investigation, the effective thermal conductivities (ETC) of periodic complex structures are evaluated. These structures are to be used as packing in Heat-Integrated Distillation Columns (HIDiC). Only high-porosity (>85%) complex structures are considered for ... En savoir plus
The presence of hexavalent chromium in dangerous concentrations in mine wastewater poses a hazard to the environment and emphasizes the development of technology in wastewater treatment is important. This study focused on the simulation of a fixed-bed adsorption column of soil and water ... En savoir plus
Climate change and concerns over the reliable supplies of hydrocarbons are aiding in the focus on Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs). The Lithium-ion battery as a better solution for energy storage in automobile applications is briefly introduced. Adverse effects ... En savoir plus
Flexible electronic devices are very sensitive against the ingress of oxygen and water vapor from the atmosphere and therefore must be protected by encapsulation with high barrier films. Typically these films contain at least two or three inorganic barrier layers separated by polymeric ... En savoir plus
In the fast growing but also highly competitive market of battery-powered power tools short charging times are essential to achieve customer acceptance and to create unique selling propositions. To prevent loss of performance and fast charging capability due to cell aging, the knowledge ... En savoir plus
Thermal enhanced oil recovery methods form the majority of the enhanced oil recovery projects worldwide. Among the thermal methods, steam injection is the most effective and most applied process in petroleum industry. The main mechanism of the steam injection method is the reduction of ... En savoir plus
