Nanoscale pipettes allow for exciting extensions of traditional current- and voltage-clamping electrophysiology experiments. However, bulk electrodynamic properties begin to break down at nanoscale openings, introducing unusual effects that must be understood in order to properly ... En savoir plus
Bioresorbable stents are providing temporary mechanical support to keep a narrowed or blocked coronary artery open and restore the blood flow and will be gradually degraded and resorbed after the healing and remodeling of arterial wall. This new generation of stents has lower rates of ... En savoir plus
The Helicon Injected Inertial Plasma Electrostatic Rocket (HIIPER) is an electric space propulsion concept being studied that utilizes a helicon source to generate a plasma and metal grids from inertial electrostatic confinement (IEC) fusion experiments to accelerate ions, generating a ...

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
This talk is for intermediate-level users of COMSOL who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics. Most turn-key Computational Fluid Dynamics packages, including COMSOL ... En savoir plus
COMSOL Multiphysics® is used to simulate electric currents in pore-level unconsolidated and consolidated packings of spherical grains. In a nutshell 1) Predefined particle size distribution curves and porosities are used to reconstruct unconsolidated packings; 2) A modified image ... En savoir plus
Electric Arc Furnaces (EAF) use graphite electrodes to strike an arc to melt scrap steel, recycling it for further use. These graphite electrodes oxidize and are consumed over time. To maintain operation new electrodes are attached to others via a joint of complex geometry and fed ... En savoir plus
The process of cold drawing a fiber over rollers is analyzed in this work to predict the temperature rise due to the heat generated during plastic deformation of the fiber. Experimental measurements on prototypes indicated an unacceptable temperature rise of greater than 100 F requiring ... En savoir plus
Thermal elastohydrodynamic lubricated (TEHL) contacts occur very frequently in drive technology and thus in gear drives. In this presentation, the implementation of a finite element based TEHL simulation approach for gear contacts in COMSOL Multiphysics® software is shown. The physically ... En savoir plus
For the lack of higher order modes, lumped element (LE) models currently used may be insufficient to predict the system of balanced-armature receiver (BAR). We develop a LE multimode model for BAR in the frequency domain based on the techniques of mode decomposition, truncation, and ... En savoir plus
