In this work, we present the modeling of V-shaped silicon micro-cantilevers. The sensitivity of different V-shaped silicon cantilevers is estimated, as a function of the geometrical dimensions of the cantilever.

This paper presents a simulation of the operation of a new type of droplet generation probe. This probe, consisting of two concentrically-arranged tubings, is immersed in a beaker of cell medium so that oil is pumped through the outer tubing at a pumping speed less than fluid is drawn into the inner tubing. In this way, droplets of cell medium are entrained into the outlet tubing forming a ...

Strained wrinkled and flat nanomembranes have different bending properties when they are released from the underlying substrate. This is caused by increased bending rigidity of the wrinkled film in one direction. We provide theoretical and numerical analysis of the directional rolling of wrinkled films, which is important for positioning rolled-up tubes on the short mesa edge during fabrication.

In the paper distributed parameter system models in the form of lumped-input/distributed-output systems are introduced and modeling of temperature fields of the die in the benchmark casting plant is presented. Temperature fields were modeled and studied using a finite element method based software package COMSOL Multiphysics and numerical models in the form of a lumped-input/distributed-output ...

Flow, concentration and temperature fields are studied with numerical and experimental methods inside a scaled-up fuel cell anode channel model. The low aspect ratio channel has a porous medium as the inferior wall where a mixing of different pH solutions occurs. Chromatic change of phenolphthalein is used to visualize concentration field and Particle Image Velocimetry (PIV) is used to visualize ...

The hyporheic zone is defined as an area where water and matter exchange through the sand, gravel, sediments and other permeable soils under and beside streams. Its impact on the hydro-system function is determined by the proportion of subsurface biogeochemical reactions and the fluxes of water exchanging with the hyporheic zone and flowing through the porous sediments. The objective of our ...

Water management is one of the most important issues of current research in the field of proton exchange membrane fuel cells (PEMFCs). Understanding the transport of liquid water in the fuel cell is necessary for the optimization of the design and the control of PEMFCs. This paper presents a mathematical model that describes the dynamic two-phase transport and the experimentally observed ...
Humusoft was founded in 1990 and has been a representative for COMSOL since 1999, for several countries in Eastern Europe. In this presentation we begin with a short overview of the and historical milestones for Humusoft. The essence of this presentation concerns the wide ranging branches in which COMSOL Multiphysics is used from the Automotive industry to the Medical. From the corporate ...
COMSOL Multiphysics (FEMLAB) Modelling of Field Enhancements as a Result of Scattering from Metallic Nanostructures
National Physical Laboratory
SERS is a candidate method for signle molecule detection. "Rough" metal surfaces or structured metal surfaces are often employed to obtain the desired enhancement through a coherent scattering process. We have modeled this process to gain a better understanding of it, and here present the results. --------------------------------- Keynote speaker's biography: Dr Jian Wang is a senior ...
