In addition to using advanced functions built-into the engine of the COMSOL Multiphysics® software, we integrate dynamic properties of rotating components that are measured or pre-computed. Here, it is shown how to integrate fluid-film characteristics and take advantage of post ... En savoir plus
This paper presents a simulation model of a rotary damper filled with a magnetorheological fluid (MRF). The most important characteristic of the MRF is the variable viscosity, which can be controlled by an external magnetic field. In the simulation model, the fluid is described as a ... En savoir plus
CV boots or gaiters are rubber like material used to cover & protect moveable or articulating components such as CV joints of a vehicle. These are primarily used to protect the articulating joint, by preventing the components from being exposed to the surrounding environment, the ... En savoir plus
Since the industrial demand in the energetic, mining and oil & gas sectors has increased exponentially these last decades, security standards and fire protection methods are extremely important not only for the employees, but also for the infrastructure involved in production areas ...

Actual trends in lightweight construction and safety-relevant technologies cause an increasing demand for reliable design of joining connections. Increasing power density and compact design require dimensioning of joints with low safety factors. Thereby additional security measures are ... En savoir plus
The present research work aims to present thermal analysis of Electrical Discharge machining. During its machining process a large amount of heat is generated due to sparking phenomena, It has been assumed that heat distribution follows the Gaussian Distribution function. As such a ...

节能、高效、紧凑已经成为制冷空调行业的发展趋势,其中强化换热技术尤为关键。因此,本文采用COMSOL软件对微型错排管换热器进行了建立二维模型,基于瞬态模型,采用流动和传热模块进行有无交变压力波的数值模拟分析。结果发现随着交变压力波的添加大大增加了速度场、压力场及温度场的波动情况,使得管内工质边界层破坏降低了传热的热阻综合空化链式理论,交变压力波能够起到强化传热的作用,提高了制冷效率,有利于推动制冷行业的发展。 En savoir plus
One of the limitations of pipelines performance and structural integrity assessment is the continuous inspection of possible leaks due to corrosion or other types of failure mechanisms. Efforts to develop new technologies started several decades ago where different inspection techniques ... En savoir plus
A comparison of the commercial code COMSOL is performed with the bench-mark solutions provided by the literature for a tall, differentially heated rectangular cavity for aspect ratios of 8, 15, 20, and 33. At small Rayleigh numbers the flow is dominated by conduction. As the Rayleigh ... En savoir plus
