We report a new type of magnetic nanofluids, which is based on a hybrid composite of nanodiamond and nickel (ND-Ni) nanoparticles. We prepared the nanoparticles by an in-situ method involving the dispersion of caboxylated nanodiamond (c-ND) nanoparticles in ethylene glycol (EG) followed by mixing of nickel chloride and, at the reaction temperature of 140°C, the use of sodium borohydrate as the ...

In this study, flow field and heat transfer of Al2O3-Cu/water micropolar hybrid nanofluid is investigated in a permeable channel using the least square method. The channel is encountered to chemical reaction, and a constant magnetic field is also applied. The bottom wall is hot and coolant fluid is injected into the channel from the top wall. The effects of different parameters such as the Reyn...

The objective of the study is to investigate thermal, electrical, and exergetic performance a hybrid photovoltaic–thermal (PVT) system under influence copper oxide (CuO) nanofluid phase change material (Vaseline (petroleum jelly)) as heat storage medium. A mathematical model was developed with help various energy-balance equations over layers system. evaluation PVT performed using pure water, C...

In this numerical study, the phase change dynamics of a 3D cylinder containing hybrid nanofluid and material (PCM) is investigated with finite element solver. The PCM consists spherical encapsulated paraffin wax, flow under forced convection regime. dynamic features process are studied for different values Reynolds number (between Re=100 300), rotational inner disk (Rew=0 size rotating (length ...

this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

This article examines entropy generation in the peristaltic transport of nanofluid in a channel with flexible walls. Single walled carbon nanotubes (SWCNT) and multiple walled carbon nanotubes (MWCNT) with water as base fluid are utilized in this study. Mixed convection is also considered in the present analysis. Viscous dissipation effect is present. Moreover, slip conditions are encountered f...

Thermal conductivity is one of the important thermophysical property nanofluid in enhancing heat transfer. To analyse transfer boundary layer problems thermal diffusivity coefficient along with embedded nano particle values will be used via various models. Many models are being utilised for theoretical analysis behaviour such as Maxwell model, Hamilton crosser model etc. In this current communi...
