We use finite elements simulations in order to study the fluid flow behavior in a chamber of a preconcentrator. We realized that most part of the fluid does not affect our preconcentrator because it is going out the chamber at high distance above it and parallel to the preconcentrator. So, we are wasting most part of our fluid and we need a lot of time to have a good concentrator factor. We ...

Microscale comprised of the scale of food biopolymers at which biochemical reactions and textural changes take place, and the macroscale was the scale of interaction of polymers with surrounding water, vapor and oil phases. Numerous novel equations such as generalized Darcy’s law based fluid transport equations for various phases; near-equilibrium equation governing phase change from liquid ...

Painted Post, NY
Microwave drying processes are critical components in the manufacture of cellular ceramic substrates and filters. The objective of this study is to develop a comprehensive model at a small scale and include all the possible physics that are important during microwave drying processes. Based on the results, conclusions are made on the importance of different factors in drying.

It is possible to obtain novel functions using nano-scaled structures and related physics that are impossible to be realized by conventional macro-scale technology. Thus, we are trying to understand the physics dominated by nanostructure and to develop the biosensing applications. Here, we exploit the interaction between materials and electrostatic field created by nanostructure, and introduce ...

Chemical reactions conducted under microwave irradiation have high reaction rates and high selectivity, but these reaction rates are not always reproducible. To achieve reproducibility, a solid-state microwave source with an ultra precise oscillator, high power amplifier module (HPA), and elliptical applicator is developed. This HPA has up to 141 W average power and generates pure 2.45-GHz sine ...

Catalytic micro-combustor represents an exciting area of research for portable power generation. Extensive research is being currently conducted on the design of the reactor and catalyst selection . However another critical element of the design will be a recuperator to minimize losses and provide energy at a more uniform temperature. The mini-recuperator must be both compact and highly ...

The separation of RBCs is needed in many biomedical devices. RBCs contain hemoglobin, which in turn consists of iron that helps transport oxygen throughout the body. The permeability of deoxygenated red blood cells is about (1 – 3.9e-6). The permeability of oxygenated red blood cells is about (1 – 9.2e-6). The permeability of plasma is about (1 – 7.7e-6). Due to the difference of permeabilities, ...

Microstrip line and rectangular waveguide are widely used as transmission lines in microwave integrated circuits and high speed interconnecting buses. In this paper, we use COMSOL Multiphysics to study electric field distribution and scattering parameters of ZnO-PCL nanocomposites when placed inside a rectangular waveguide and as an overlay on a microstrip at microwave frequency (8-12 GHz). We ...

Stenosis is a localize plaque that cause the vessel wall narrowed and causing an alternation in the flow structure which consequently reduced the fluid flow passing to the other organs and tissues. Previous researchers had proven that the formation of stenosis could disturb the normal hemodynamics in blood rheology. Generalized power law model is the best model describing a narrowing blood ...
