one of the effective methods to improve the thermal efficiency of solar collectors is using nanofluids as the coolant. the present study experimentally investigated the effect of sio2/water nanofluid with 1% mass fraction on the performance of a symmetric collector, i.e. conical solar collector. the conical solar collector with 1 m2 area and normal to the earth was tested in ahvaz, a city in th...

The thermal performances of a minichannel heat sink are experimentally investigated for cooling of electronics using nanofluid coolant instead of pure water. The Al2O3–H2O nanofluid including the volume fraction ranging from 0.10 to 0.25 vol.% was used as a coolant. The effects of different flow rates of the coolant on the overall thermal performances are also investigated. The flow rate was ra...

ABSTRACT: Excess fluoride ion (F) in drinking water causes harmful effects such as dental and skeletal fluorosis. Hence, its concentration in drinking water must not exceed a certain range. This study investigated the removal of F from aqueous solutions with CuO nanoparticles using a range of experimental approaches, including pH, adsorbent dose, contact times, and initial F concentration. The ...

This study aims to improve the performance of vehicle's cooling system called radiator, which is part increasing energy efficiency. Research has been done investigate convective heat transfer hybrid nanofluid, using CuO and TiO2 nanoparticles water-ethylene glycol (RC) as base fluids on a radiator. The mass concentration varied from 0.25 %, 0.30 0.35 %. For preparation nanofluid through two-ste...

This paper is devoted to study the effect of heat transfer on temperature distribution in a superheated liquid during growth vapour bubbles immersed different types nanoparticles/water nanofluids between two-phase turbulent flow.

Nanofluid has great potentials in heat transfer enhancement and entropy generation decrease as an effective cooling medium. Effects of Al2O3-water nanofluid flow on entropy generation and heat transfer performance in a rectangular conventional channel are numerically investigated in this study. Four different volume fractions are considered and the boundary condition with a constant heat flux i...
