using of nanofluids and ducts with corrugated walls are both supposed to enhance heat transfer, by increasing the heat transfer fluid conductivity and the heat transfer area respectively. use of a diverging duct with a jet at inlet section may further increase heat transfer by creating recirculation zones inside the duct. in this work two-dimensional incompressible laminar flow of a nanofluid e...

This paper deals with the role of hydrodynamic conditions using a filter-press-type FM01-LC electrochemical reactor equipped with 2D (plate) and 3D (mesh) boron doped diamond (BDD) electrodes for the incineration of recalcitrant organic matter. A strategy for the electrochemical incineration of different organics, such as p-cresol, o-cresol, indigo textile dye and vinasses, is shown. The curren...

vanillin offers interesting possibilities for corrosion inhibition because of its safe use and highsolubility in water. the effect of vanillin on the corrosion inhibition of aisi 304 stainless steel in0.5m h2so4 solution has been studied using potentiodynamic polarization and electrochemicalimpedance spectroscopy (eis). furthermore, this paper demonstrates that the electrochemical noise(en) tec...

due to the importance of weed control and the limitations of mechanical methods in some places, in this research the water jet cutting for weed control was investigated. the cutting tests were performed on camel thorn weed in shahid bahonar university of kerman. the water jet pressure of 90 bars was achieved with the aid of a suitable pump. the cutting time was studied in a completely randomize...

Abstract An eco-friendly green corrosion inhibitor Commiphora Mukul was tested for its efficacy to control material loss in 6061 aluminum alloy under collective influence of mechanical erosion and electrochemical a submerged jet impingement rig. Electrochemical techniques were utilized the current investigation which consisted potentiodynamic polarization impedance spectroscopy. The effect temp...

The effect of a combined system of the bed suction and jet injection as a pier-scour countermeasure on the turbulent flow field is studied in a laboratory flume using an Acoustic Doppler Velocimeter (ADV). The three components of the velocities in the vertical symmetry plane in the equilibrium scour hole in front and rear of the pier under 3-jet injections and bed suction rate Qs/Q0 = 2%located...

The stability of hydrophobic surface has an important influence on the application superhydrophobic function. destruction micro-nano structures material is main factor leading to loss property. In order improve corrosion resistance surface, Ni-Co-BN nanocomposite coatings with property were prepared 45 steel by two-step jet electrodeposition. morphology, water contact angle, and samples measure...

In this study, the missile staging process by implementing a side-injected jet is simulated numerically. The problem is considered to be axisymmetric and the thin shear layer approximation of Navier-Stokes equations along with an algebraic turbulence model is used in a quasi-static form for the calculations. The free stream corresponds to a very high altitude flight condition with a Mach number...
