Mohammad Reza Safaei,Ahmad Hajizadeh,Masoud Afrand,Cong Qi,Hooman Yarmand,Nurin Wahidah Mohd Zulkifli +5 more
TL;DR: In this article, the experimental data on the thermal conductivity of EG based hybrid nanofluid containing zinc oxide and titanium oxide have been used for training the artificial neural network and three two-variable correlations have been proposed using curve-fitting on experimental data.
Journal ArticleDOI
Experimental study on the flow and heat transfer characteristics of nanofluids in double-tube heat exchangers based on thermal efficiency assessment
TL;DR: In this paper, the thermal performance and pressure drop of TiO2-H2O nanofluids in double-tube heat exchangers were investigated, and the influence of the thermal fluid (water) volume flow rates, nanoparticle mass frictions (ω 0.0, 0.1%, 0.3% and 0.5%) on the heat transfer rate was investigated.
Journal ArticleDOI
Experimental and numerical study of natural convection in a square enclosure filled with nanofluid
TL;DR: In this paper, a 2D two-phase Lattice Boltzmann model considering interaction forces (gravity and buoyancy force, drag force, interaction potential force and Brownian force) between nanoparticles and base fluid is developed for natural convection of nanofluid, and is applied to simulate the flow and heat transfer of Al 2 O 3 -water nano-drone in the square enclosure by coupling the density distribution (D2Q9) and the temperature distribution with 4-speeds.
Journal ArticleDOI
A techno-economic investigation of 2D and 3D configurations of fins and their effects on heat sink efficiency of MHD hybrid nanofluid with slip and non-slip flow
TL;DR: In this paper, the effects of fin's length and different types of heat sinks with various lengths on the entropy generation rate (EGR) and Nusselt number (Nu) were investigated at different Richardson numbers (Ri) considering slip and non-slip conditions.
Journal ArticleDOI
Two-phase lattice Boltzmann simulation of the effects of base fluid and nanoparticle size on natural convection heat transfer of nanofluid
TL;DR: In this article, the effects of two kinds of base fluid (H 2 O and Ga) and three different nanoparticle radiuses (20, 40, and 80 nm) on the natural convection heat transfer of a rectangular enclosure filled with Al 2 O 3 -Ga and Al 2 o 3 -H 2 -Ga nanofluid at different Rayleigh numbers (Ra ǫ = 10 3 and Ra  = 10 5 ) are discussed based on a two-phase lattice Boltzmann method.
