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 ...

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...

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...

This response refutes point (i) in the Ayres comment’s abstract. It argues that at its heart responsive regulation is about seeking strategies that will render regulation more relational when it counts. This is possible even in domains like tax compliance where 99 per cent of the routine regulatory action occurs without face-to-face encounter. A number of critiques in the special issue are embr...

I t is possible to think of the responsibilities of corporate managers on either the macro level--accountable to w h o m o r the micro level--accountable for what. Discussions of managerial responsibilities on the macro "to whom" level have been ongoing for years, certainly since Berle and Means (1936) first noted the replacement of company owners by professional managers, without reaching a wi...

This work presents a novel method to assess the condition of Caenorhabditis elegans (C. elegans) through a resistance measurement of its undulatory locomotion speed inside a micro channel. As the worm moves over the electrode inside the micro channel, the length of the electrode changes, consequently behaving like a strain gauge. In this paper, the electrotaxis was applied for controlling the d...

The problem of development microequipment is discussed. This paper contains description of the main problems connected with micro mechanical equipment developing, requirements to the micro machine tools properties, design and control systems of the prototypes of first generation machine tools, and applications of micro equipment. The mayor idea of this paper is to show the experience of the Lab...

Shock/boundary layer interaction (SBLI) is an undesirable phenomenon, occurring in high-speed propulsion systems. The conventional method to manipulate and control SBLI is using a bleed system that involves the removal of a certain amount of mass of the inlet flow to control boundary layer separation. However, the system requires a larger nacelle to compensate the mass loss, larger nacelles con...
