Micro-Channel Heat Sink is a heat exchanger which is used to control the temperature of electronic devices with high heat flux. A comprehensive thermal model for the micro-channels should include three dimensional conduction analysis in the solid body together with three dimensional developing fluid flow as well as heat transfer analyses in the fluid section. This paper reports on a research ...

We present an experimental study of a new regime of monodisperse micro–droplet generation that we named the balloon regime. A dispersion of oil in water in a T–junction microfluidic system was studied. Several microfluidic devices having different cross– sections of the continuous and the dispersed phases micro–channels were tested. This new regime appears only for low dispersed phase velocity....

objective: in this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. methods: the base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. lorentz electric force, which is used as stimulating flow factor, is created by appl...

Architectural limitations in many situations make it necessary for the RC shear walls to be extended in plan in different directions at a single location that makes them a 3D configuration. Analysis of such walls is very challenging. In this research about 450 cases of 3D shear walls are considered with different shapes and heights. L, T and H-shape walls are studied. They are nonlinearly analy...

This paper demonstrated a multi-channel Wavelength-Division-Multiplexing (WDM) system using photonic crystal structures. The system consists of a waveguide that realized by a defect row of photonic crystal and high Q-value micro-cavities. Two-Dimension (2-D) Finite-Difference-TimeDomain (FDTD) method is performed for simulation in this paper. The results showed good ability to filter an inciden...

In this work, we investigate crystallization from droplets formed on micro-patterned surfaces. By solvent exchange in a micro-chamber, ternary solution consisting of model compound beta-alanine, water, and isopropanol, was displaced by flow isopropanol. the process, oiling-out crystallized. Our results showed that shape size crystals surfaces could be simply mediated conditions exchange. Varyin...
