in this paper, finite element model of woven fabric target has been investigated which is impacted by a cylindrical projectile. fabrics are impregnated with shear thickening fluid (stf). the effects of the (stf) have been considered as frictional effect. the stf has been made (nano silica and polyethylene glycol (peg)) and then diluted by ethanol proportion of 3:1. yarn pulling out test from in...

The objective of the present work is to conduct investigations leading to a more complete explanation of single phase natural convective heat transfer in an enclosure with fin utilizing nano fluids. The nano fluid used, which is composed of Aluminum oxide nano particles in suspension of Ethylene glycol, is provided at various volume fractions. The study is carried out numerically for a range of...

In this paper, an experimental work was investigated on nanorefrigerant .Nano Al2O3-PAG oil was used as nano-refrigerant in R134a vapour compression refrigeration system . An experimental setup was designed and fabricated in the lab. The system performance was investigated using energy consumption test and freeze capacity test. The results indicate that Al2O3 nano refrigerant works normally and...

Abstract It is a well-known fact that functional effects like relaxation and retardation of materials, heat transfer phenomena occur in wide range industrial engineering problems. In this context, mathematical model developed the view Caputo fractional derivative for Oldroyd-B nano-fluid. Nano-sized particles copper (Cu) are used to prepare nano-fluid taking water as base fluid. The coupled non...

Every year, millions of people are suffering from bone defect arising from trauma, tumor or bone diseases. Therefore, there is a growing need for the development of biocomposites with excellent bioactivity and compatibility. In this study, nano-hydroxyapatite was elaborated by using polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) under mild temperature condition. Comparison with pure nan...

This paper deals with the double-diffusive boundary layer flow of non-Newtonian nano-fluid over a stretching sheet. In this model, where binary nano-fluid is used, the Brownian motion and thermophoresis are classified as the main mechanisms which are responsible for the enhancement ofthe convection features of the nanofluid. By means of the successive approximation method the governing equation...

The use of ultra-thin, i.e., monolayer films plays an important role for the emerging field of nano-fluidics. Since the dynamics of such films is governed by the interplay between substrate-fluid and fluid-fluid interactions, the transport of matter in nanoscale devices may be eventually efficiently controlled by substrate engineering. For such films, the dynamics is expected to be captured by ...

In this study first and second law analyses of non-Newtonian nano-fluid flow through an annular cylinder filled with water- CMC/TiO2 by considering temperature jump slip velocity were investigated numerically. The single-phase was developed for heat transfer flow. impact Reynolds number, nano-particles volume fraction, jump, on Nusselt numbers entropy generation evaluated the findings discussed...

OBJECTIVES Silver has long been known as a strong antimicrobial and disinfectant. Several types of nano-silver coated products have been developed. However, the antimicrobial and disinfectant characteristics of nano-silver have not been well studied. The aim of this study was to investigate the effect of nano-silver on allergic inflammation in a mouse model. METHODS Female BALB/C mice were se...

Fluid phase endocytic uptake of external solutes in plant cells was further substantiated using artificial polystyrene nano-spheres (40 nm) and CdSe/ZnS quantum dots (20 nm). Both types of artificial nano-particles were taken up by sycamore-cultured cells. However, whereas polystyrene nano-spheres were delivered to the central vacuole, CdSe/ZnS nano-dots were sequestered into cytoplasmic vesicu...
