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

Synthetic jet actuators enhance flow control by generating pulsatile jets with zero net mass flux. There is a need to develop a computationally inexpensive model that can generate optimal geometric actuator designs of maximum jet performance. This work investigates the multi-physics ...

We discuss the implementation of artificial boundary conditions for stationary Navier-Stokes flows past bodies in the half-plane, for a range of low Reynolds numbers. When truncating the half-plane to a finite domain for numerical purposes, artificial boundaries appear. We present an ... En savoir plus

Reperfusion injury is caused by the rapid restoration of blood flow to oxygen-starved tissue. Animal studies show that intermittent periods of occlusion (also called post-conditioning) during reperfusion can limit tissue damage to vital organs such as the heart and brain. These studies ...

Seasonal thermal energy storage systems are key enablers of future low-carbon and flexible energy infrastructures. Among the different storage technologies, water-gravel thermal energy storage (WGTES) offers a robust, cost-effective, and environmentally sustainable solution for large ... En savoir plus

This paper focuses on the acoustic modeling and simulation of a simplified minute repeater watch using the Boundary Element Method (BEM). The overarching objective is to optimize the hammer's impact location on the watch's gong (timbre) to enhance both the radiated acoustic intensity and ... 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

Superparamagnetic micro beads offer some  attractive applications in biological and biomedical fields. Some of the important applications include manipulation and separation of cells, isolation of specific cells, active drug delivery, magnetic cell separation, separation of proteins, and ...

Deformation of food packaging materials due to internal pressure buildup during sterilization is a critical concern for packaging integrity and product safety, particularly in non-rigid containers like polypropylene (PP) trays for ready-to-eat meals. (Dutta et al., 2024b). Internal ... En savoir plus

Deformation prediction is an important part of the structure stability analysis. However, the deformation of bank protection structure which is affected by many factors, such as structural stiffness, earth pressure and hydrostatic pressure. It contains a complex mechanical process, which ... En savoir plus
