The rapid advancement in technology recent years has shown that nanofluids are very vital to further development science and technology. Moreover, many industrial specifications cannot be met by allowing natural convection only, hence the need incorporate forced into a single flow regime. research aims quantify mixed convective two-phase past vertical permeable surface Brinkman-Extended Darcy p...

The natural convection flow of a second-grade hybrid nanofluid along vertical plate is investigated. effects variable heat flux and magnetic field are considered. governing equations for the momentum energy transport reduced to dimensionless equations. finite difference method used solve obtained by stream-function formulation. A comparison between present results relevant published gives good ...

This paper reports a newly fabricated nanophyto-modified wound dressing with microbicidal and anti-adherence properties. Nanofluid-based magnetite doped with eugenol or limonene was used to fabricate modified wound dressings. Nanostructure coated materials were characterized by TEM, XRD, and FT-IR. For the quantitative measurement of biofilm-embedded microbial cells, a culture-based method for ...

Numerical investigation on the generality of nanoparticle velocity equation had been done on the previous published work. The three dimensional governing equations (continuity, momentum and energy) were solved using finite volume method (FVM). Parametric study of thermal performance between pure water-cooled and nanofluid-cooled are evaluated for volume fraction in the range of 1% to 4%, and na...

The present study investigates the unsteady, two dimensional, laminar flow of a nanofluid over a stretching sheet with thermal dispersion in the presence of MHD and variable suction is studied. Two water based nanofluids containing Copper Cu, Titanium dioxide TiO2 nanoparticles are considered in this study. Using the similarity transformations, the governing equations have been transformed into...

Nanofluids are engineered fluids that contain a suspension of nanoparticles in a pure substance. Nanoparticles can be any variety of metals, metal oxides, or ceramics. They have been shown to increase heat transfer properties such as thermal conductivity, convective heat transfer, and critical heat flux(CHF). An optical probe used to detect phase was used to measure the void fraction during boi...

in this paper, the effect of the brownian term in natural convection of cuo-water nanofluid inside a partially filled porous cavity, with internal heat generation has been studied. it is assumed that the viscosity and thermal conductivity of nanofluid consists of a static part and a brownian part of which is a function of temperature and the volume fraction of nanofluid. because of internal hea...

This paper presents results of investigations on the application of CuO-water nanofluids for intensification of convective heat transfer. Performance of nanofluids with 2.2 and 4.0 vol.% CuO NPs (nanoparticles) content were examined with regard to heat transfer coefficient and pressure losses in case of turbulent flow in a tube. Negligible impact of examined nanofluid on heat transfer improveme...
