This paper aims to develop models for the thermal conductivity and viscosity of hybrid nanofluids aluminium oxide titanium dioxide (Al2O3-TiO2). The study investigates impact fluid temperature (283 K–298 K) on performance a plate heat exchanger using Al2O3-TiO2 with different particle volume ratios (0:5, 1:4, 2:3, 3:2, 4:1, 5:0) prepared 0.1% concentration in deionised water. Experimental evalu...

The generation of entropy and mixed convection in a nanofluid-filled 3D wavy tank containing rotating cylinder is investigated. top surface the heated all vertical surfaces are assumed to be adiabatic, while bottom horizontal remains isothermally cold. contains solid saturated with an Al2O3–water nanofluid. numerical simulations using FEM performed for Richardson number (0.01≤Ri≤100), nanoparti...

In this study, different nanofluids with phase change behavior were developed by mixing a molten salt base fluid (selected as phase change material) with nanoparticles using the direct-synthesis method. The thermal properties of the nanofluids obtained were investigated. These nanofluids can be used in concentrating solar plants with a reduction of storage material if an improvement in the spec...

As a model for electroconductive nanomaterials processing, the article examines incompressible mixed convection nanofluid flow with convective heat transport from stretching sheet under impact of Joule heating and radiative flux. The transformed non-linear boundary value problem is solved robust Chebyshev collocation technique. Validation conducted earlier published results. Nanoparticle concen...

The present numerical work deals with the optimization of micro-channel heat sink using irreversibility analysis. nanofluid Al2O3-water different nanoparticles concentration and temperature-dependent property is chosen as a coolant. flow considered fully developed, steady, laminar in constant cross-section circular channels. Navier-Stokes energy equations are solved for single-phase total mass ...

This research is a novel experimental work on cooling solar panels using hydrogel beads saturated with Al2O3 water based nanofluid. Nanofluid of concentrations 0.1, 0.25, and 0.5% wt. were used compared to the only cooled uncooled PV panels. A passive system was created three layers nanofluid hydrogels attached back surface exposed panels, fixed radiation intensities 800 1000 W/m2. Using 0.5%wt...

turbulent mixed convection of a nanofluid (water/al2o3, φ=.02) has been studied numerically. two-phase mixture model has been used to investigate the effects of nanoparticles mean diameter on the flow parameters. nanoparticles distribution at the tube cross section shows that the particles are uniformly dispersed. the non-uniformity of the particles distribution occurs in the case of large nano...
