The visual accommodation is a complex biomechanical & optical process. Today in vivo imaging technologies do not allow to measure the eye components material properties, such as the refractive index or the stiffness: these properties are essential to understand and diagnose the ... En savoir plus

One of the most effective treatments for diabetes type 1 and 2 is the administering Insulin. The design of positive volumetric insulin pump is significantly a multiphysics problem where the volumetric change of the main pump chamber and the pumped fluid are directly coupled. We used ...

Introduction In recent years there has been a focus on using topology optimization in the field of acoustics [1,2], whereas previously the technique has been applied mostly within structural mechanics, thermodynamics, and fluid dynamics [3]. This paper describes the mathematical basis ... En savoir plus

Introduction Most current thermoregulation models represent the body in significantly simplified forms, e.g., cylinders or spheres. These simple geometries do not fully represent the complexity of bones, organs, etc. contained in the human body. Modern medical technologies allow for more ... En savoir plus

The multilayer composite single mass cantilever is a MEMS energy harvester structure. The vibrating structure is under vacuum in hermetic MEMS. However, out-gassing during process integration and fabrication would cause air molecules (e.g. hydrogen, nitrogen, argon, water vapor, oxygen, ... En savoir plus

Our current research is focused on thermal Marangoni instabilities in sessile ethanol drops which develop spontaneously during evaporation. Our current problem for numerical model is 3D unsteady with moving interface of a sessile drop under forced evaporation and showing internal flow ... En savoir plus

Different modules and capabilities of COMSOL Multi-physics software i.e. Fluid Flow, Moving Mesh and Global ODEs/DAEs are combined and applied to study the accelerating of a projectile inside a so-called "vacuum bazooka". Initially, the projectile is at rest in a partially vacuumed tube. ... En savoir plus

In this work we present a novel approach to enhance energy efficiency in cooling intake air for air conditioning (AC) systems in harsh environments using geothermal energy. We developed a 3D finite element model to simulate the heat transfer between underground soils/gravels and cooling ... En savoir plus

An abdominal aortic aneurysm (AAA) is a bulge formed in the large blood vessels that supply blood to the abdomen, pelvis, and legs. A fluid structure interaction model was developed in a 3D aortic aneurysm model, which was constructed from abdominal CT scan images. Combining medical ... En savoir plus

Our goal is to reproduce the key features of carangiform swimming by running 2D simulations which fully exploit the Fluid-Structure Interaction interface of COMSOL Multiphysics software. Fish swimming is an important area of research, with relevant developments on biomechanics, robotics ... En savoir plus
