Scanning tunnelling microscopy/spectroscopy reveals significant electronic communications between edge-on biphenyl moieties of a benzene core derivatised biaxially with four ethynyl-biphenyls. The key to the successful assembly of conjugated 1D nanowires is the rotatable features of ethynyls, which allow dual adaptability of edge-on and face-on orientations for the aromatic rings.

A numerical simulation of a turbulent flow water in three shell and tube heat exchangers equipped with 6, 8, 10 segmental baffles as the working fluid at Reynolds numbers ranging from 24327, 33356, 42569 are performed. The conservation equations mass, momentum energy solved by finite volume method based on SIMPLE algorithm for coupling velocity-pressure, mathematical model k-ε within Fluent sof...

Combustion instability caused by the amplification of sound waves is called acoustic or high-frequency instability, which can cause severe damage to system. Adding baffles one methods passive control. Depending on geometry chamber and type application, different are used. In this research, effect longitudinal corrugated baffle characteristics combustion investigated numerically. The quality eac...

Turbulent flow in complex geometries receives considerable attention due to its importance in many engineering applications. It has been the subject of interest for many researchers. Some of these interests include the design of storm water channels. The design of these channels requires testing through physical models. The main practical limitation of physical models is the so called “scale ef...
