The study of hybrid nanofluid and its thermophysical properties is emerging since the early 2000s purpose this paper to investigate flow over a permeable Darcy porous medium with slip, radiation shrinking sheet. Here, consists Cu/water as base Al2O3–Cu/water works two distinct fluids. governing ordinary differential equations (ODEs) obtained in are converted from series partial (PDEs) by approp...

The conventional liquids have some limitations regarding the thermal properties. The nanoparticles addition is one of the techniques which can modify them. In this research, heat transfer coefficient (h) and pressure loss (Δp) of various nanofluids containing Al2O3, SiO2 and MgO nanoparticles dispersed in water in an annular tube with constant wall temperature were numerically considered. Accor...

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...

The experimental study of the heat transfer coefficient nanofluid plays a significant role in improving rate exchanger. A natural convection apparatus was used to suspension Al2O3 nanoparticles water-ethylene glycol mixture base fluid. effects input, nanoparticle volume fraction, and fluid concentration on were studied using 23 full factorial design matrix (16 runs) MINITAB Design software. lev...

In cooling water systems, towers play a critical role in removing heat from the water. Cooling systems are commonly used industry to dispose waste heat. An upward spray was especially designed and investigated this work. The effect of two nanofluids (Al2O3/ water, black carbon /water) on velocity temperature distributions along reverse tower at various concentrations (0.02, 0.08, 0.1, 0.15, 0.2...

This study presents the improvement of thermal performance of heat pipe using copper nanofluid with aqueous solution of n-Butanol. The nanofluids kept in the suspension of conventional fluids have the potential of superior heat transfer capability than the conventional fluids due to their improved thermal conductivity. In this work, the copper nanofluid which has a 40 nm size with a concentrati...

The current study experimentally examines the impact of coil pitch on heat transfer behavior and friction factor through helical coils for ?- Al2O3/Distilled water nanofluid turbulent flow. These tests were conducted with pitches 20, 35, 50 mm. nanoparticle volume fraction was 0.1%. nanoparticles in a 0.1% concentration increased rate compared to those distilled water. Increases also resulted g...
