a micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. governing equations were solved base on the finite volume method with fluent software. in upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. two sections were separated with solid part which played as heat exchanger and trans...

The theoretical analysis of steady mixed convection with Arrhenius-controlled heat flow for a viscous and an electrically-conducting fluid traveling across isothermally heated vertical parallel plate in slit micro-channel is investigated this study. One wall had super-hydrophobic slip temperature spike, while the other did not. A semi-analytical technique (perturbation series) was employed to a...

This thesis first proposes a hybrid ac/dc micro-grid and its coordination control for reducing the processes of multiple conversions in an individual ac or dc grid. Renewable energy based distributed generators (DGs) play a dominant role in electricity production, with the increase in the global warming. Distributed generation based on wind, solar energy, biomass, mini-hydro along with use of f...

The present research aims to identify the differences and similarities that may exist between variables associated with logistics management of business organizations based on their size. For this, a comparison was made 992 companies in Ecuador, where four types were represented: micro, small, medium large, proportion structure composition country’s presents. results showed, by applying hypothe...

Micro-electrochemical additive manufacturing (μECAM) is reverse of electrochemical micro-machining (μECM) which used for selective and localized deposition material on a substrate. It can be to manufacture small sized parts or deposit functional metal coatings conductive surfaces. As the process contactless generates negligible joule heating, deposited free from heat affected zones has low inte...

The proposed photovoltaic Micro Inverter is based on three port flyback with one port dedicated to power decoupling function so the decoupling capacitance is reduced and hence the long lifetime film capacitor is used. One of the two transformers and one capacitor is used for decoupling function. The decoupling capacitor functions as energy storage as well as snubber capacitor to recycle the tra...

Micro CHP, installed in individual homes, will in time remove a substantial electricity demand on a dynamic basis at the low voltage level, and may, in some instances, neutralise or even reverse the power flows in distribution transformers. This will clearly have economic consequences for the Distribution Network Operator (DNO) in terms of lost revenue, but will also have profound consequences ...

Microemulsions are psuedohomogeneous mixtures which may show special performance towards reaction equilibria, nanoscale synthesis and reaction dynamics. Rate of reaction are most often accelerated in microemulsion media compared to that in water. This study is an effort to review some important reaction kinetics measured in reverse micro emulsion media. In the same time some pioneering research...
