COMSOL® models of basal body deformation using the Beam Interface are compared to electron tomograms of Tetrahymena thermophila basal bodies high-pressure frozen while undergoing beating deformation. This approach provides insight into the nanoscale structures and internal forces ... En savoir plus

While electrostatic actuators feature prominently among the most widely employed classes of actuators for microelectromechanical systems (MEMS), conventional embodiments of these devices (e.g., parallel plate structures) notoriously suffer from several significant drawbacks. Most ... En savoir plus

Water removal during paper and board manufacturing is an intensive energy process. The dewatering process generally consists of four stages wherein the last stage is comprised by thermal drying in where remaining water in fibres are evaporated on steam-heated cylinders. The thermal ... En savoir plus

Valves are widely used to control fluid flow in various engineering applications. It’s crucial to study the flow characteristics inside the valve and the fluid-structure interaction between the fluid and valve’s sleeve for design, optimization and improvement of valves. However, because ... En savoir plus

The paper attempts to give a contribution to the dynamic analysis of musical instruments. A multidisciplinary approach oriented to the study of mechanical, structural, vibratory and acoustical phenomena related to stringed instruments is discussed. The case study focused in this paper ...

In this paper, we present a comprehensive study on the influence of anatomical shapes on the speed of blood flow in the left atrial appendage (LAA) using Computational Fluid Dynamics (CFD) Module in COMSOL Multiphysics®. The LAA itself can serve as a potential origin of blood clots, ... En savoir plus

Microbubble oscillations in the presence of ultrasound wave inside blood vessel have been widely studied for therapeutic applications like drug and gene delivery[1], blood-brain barrier opening[2], and lysis of blood clot[3] and cell membrane[4]. An oscillating bubble exerts stresses on ... En savoir plus

Solenoid valves control fluid flow by using the passage of an electric current to produce a magnetic field that controls the displacement of a pre-tensioned plunger. As the electric current increases, the induced force causes the plunger to move upward against the force exerted by a ... En savoir plus

Currently, there is a great interest in the study of gels, especially their transport or release properties. Hydrogels have countless definitions, but generally speaking, they are hydrophilic systems with a three-dimensional structure that tend to swell and hold large amounts of water ... En savoir plus
