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

MEMS microphones have been widely adopted in a variety of consumer electronic systems. To ensure clear speech transmission and avoid degradation of important signals, careful tuning of microphone port geometry is essential to mitigate wind-induced airborne noise. This additional noise ... En savoir plus

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 paper describes using thermal structural interaction to model the shrinkage behavior in cement paste under drying. An inverse method of combining the finite element analysis and the least-squares method is implemented to fit experimentally determined shrinkage in order to obtain ... En savoir plus

Energy harvesting from a fluid flow using piezoelectric materials is a relatively recent topic that has been investigated experimentally and numerically [1, 2]. Its possible application in natural water currents represents an interesting strategy to easily harvest renewable energy from ... En savoir plus

Recognized for its potential as a sustainable food source, seaweed farming has become pivotal in tackling future food security concerns, necessitating innovative solutions to achieve optimal, high-yield, and commercially viable production [1]. This work addresses gaps in aquaculture ... 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

INTRODUCTION: The paper illustrates the use of COMSOL for obtaining the solution Ψ(x,y,t) as a solution to the time dependent nonlinear Schrödinger equation (NLSE). COMSOL previously was used to solve the time dependent NLSE in Ref.[1] as applied to quantum mechanics, however this is the ... En savoir plus

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
