A Computational Fluid Dynamics study has been performed for a Gas Electron Multiplier (GEM) detector of high energy charged particles, currently under development as part of a new tracker of the high luminosity spectrometers in Hall A at Jefferson Lab. By gradual modifications of the geometry simulated in COMSOL, the design of the frame separating two GEM foils has been optimized with the aim ...

We developed the dual-micropillar-based microfluidic platform to control cellular behavior. The 4×4 dual micro-pillar based platform consists of 16 circular-shaped outer micropillars and 8 saddle shaped inner-micropillars. We simulated various shapes of inner micropillars to analyze the shear stress inside the inner micropillar. Therefore, this dual-micropillar-based microfluidic platform could ...

The radiation force effects on the surface displacement can be calculated by solving the Navier-Stokes equation with appropriated boundary conditions. The surface deformation can be described by the radiation pressure as well as those forces due to gravity and surface tension. We used the photomechanical mirror (PM) method to measure the time-evolution of the nanometer deformation generated on ...

There are two types of vertical axis wind turbine, drag-type and lift-type. Drag type wind turbine can rotate in low speed wind condition, although its rotation speed is low. Lift type wind turbine can rotate at higher speed, although it works only in high speed wind condition. This study investigates new blade profile that realize rotation in low wind speed condition and higher rotation speed ...

Most conventional wastewater treatment processes are quite energy-intensive. Global wastewater production is increasing due to growth in population, industrialization, and urbanization, creating an urgent need for energy-efficient wastewater treatment technologies. Moreover, waste streams (industrial and domestic) have drawn renewed interest as resources for water, energy, and product recovery. ...

The ability to artificially produce silk fibers has great commercial, industrial and scientific implications. Much has been made of their remarkable mechanical properties but few have considered how they are imparted on the initially liquid silk feedstock.1 I am exploring how silk duct geometry affects the fibers produced as by understanding the flow conditions within the model, and comparing ...

Slot coating is a widely used commercial process for applying one or more thin layers to a substrate such as paper, fabric, film or other material. In many cases, a highly uniform thickness is required, where a coating head that has been corrected for use with a Newtonian fluid may not produce a uniform coating when used with non-Newtonian fluids. With a multiphysics calculation involving the ...

The rheological behaviour of a biphasic material is quite difficult to model because of the difficulties to represent the evolution of the space position of each solid particle in the solid matrix. The first part of this study consider an equivalent material by homogeneisation method. The main point of this first part was the representation of the rotation of the rheological mobile. The second ...

A frequently occurring geometry for heat exchangers is that of a long tube wound into a helix or spiral around a core volume. There is to be heat exchange between the tube and the gases (or solids) in the core. However, the length scales of these two parts of the geometry are very different, thus complicating the interface between the tube and the core processes. Usually, the tube is too ...

The paper outlines a two-dimensional computational methodology and presents results for laminar/laminar condensing flows inside mm- scale ducts. The methodology has been developed using MATLAB/COMSOL platform and is currently capable of simulating film-wise condensation for steady and unsteady flows. The results obtained are shown to be in agreement with an independently developed quasi-one ...
