We present a problem-adapted finite element model, which enables the design of a novel type of a highly miniaturized, electrostatic MEMS membrane pump, as well as the investigation and the optimization of its operation. The electro-mechanical actuation scheme constitutes a strongly ... En savoir plus

This study focuses on optimizing the lengths of various structural components around a cylinder to minimize drag. Using COMSOL Multiphysics, numerical simulations involving Laminar Flow were performed. Key components optimized include an arrowhead positioned upstream and two flaps ... En savoir plus

The mitral valve apparatus is a complex and refined mechanism located between the left atrium and the left ventricle of the heart which can manifest various kinds of pathologies. In order to support identification of potentially critical conditions resulting from some typical ... En savoir plus

As the demand for lightweight fibrous insulation materials in aerospace [1] and automotive [2] applications increases due to their benefits in reducing carbon footprints and costs [3], accurate prediction of thermal properties becomes crucial, particularly before production. The thermal ... En savoir plus

The ever-growing complexity of samples which need to be processed in e.g., environmental and biomedical/biochemical research, demand higher efficiencies of analytical techniques. Liquid chromatography (LC), mass spectrometry, among others, are analytical techniques that revolutionized ... En savoir plus

Bimetallic mechanical parts made of steel and bronze combine in an optimal manner the mechanical properties of the steel and the excellent anti-friction characteristics of the bronze. These properties make applications possible in various high-tech domains such as aviation, energy and ... En savoir plus

Ultrasonic nondestructive testing (NDT) is extensively used in fields like medicine, oil and gas, and aerospace to inspect materials without causing damage. However, developing experimental setups and prototypes can be costly and time-consuming. This study employs advanced computational ... En savoir plus

This paper describes using thermal structural interaction to model the shrinkage behavior in cement paste under drying.
