With the growing consumer demand in electronics field, sustainable and effective cooling approaches are imperative to maximize operational efficiency. Heat pipes shave a major consideration field of heat transfer modern era miniaturization equipment. In current trends, proportion custom-designed electronic chips is increasing, given space constraints application. Additionally, use nanofluids ha...

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...

In the present study, mixed convection laminar flow around an adiabatic body in a Lid-driven enclosure filled with nanofluid using variable thermal conductivity and variable viscosity is numerically investigated. The fluid around the body in the enclosure is a water- based nanofluid containing Al2O3 nanoparticles. The Vertical enclosure’s walls are maintained at constant cold temperature an...

In this paper, Turbulent mixed convective heat transfer of water and Al2O3 nanofluid has been numerically studied in a horizontal tube under non-uniform heat flux on the upper wall and insulation in the lower wall using mixture model. For the discretization of governing equations, the second-order upstream difference scheme and finite volume method were used. The coupling of pressure and veloci...

In the present study, heat transfer characteristics, namely, coefficient, Nusselt number, pressure drop, friction factor and performance evaluation criteria are evaluated for water, Al2O3 Al2O3/Cu nanofluids. The effects of Reynolds volume fraction composition nanoparticles in hybrid nanofluid analyzed all characteristics. single particle nanofluids flowing through a plain straight tube which i...

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...

In this study, the heat transfer rate of Al2O3-water nanofluid-flow in a tube with twisted tape inserts is experimentally examined. The insert can cause swirling region fluid-flow which will enhance coefficient. On other hand, have great influence on pressure drop. It known that nanoparticles and may both increase fluid. Thus, it tried to demonstrate combined effect phenomena, experimentally. w...

This article reports a recent study on the application of a two-phase closed thermosyphon (TPCT) in a thermosyphon for economizer (TPEC). The TPEC had three sections of equal size; the evaporator, the adiabatic section, and the condenser, of 250 mm × 250 mm × 250 mm (W × L × H). The TPCT was a steel tube of 12.7-mm ID. The filling ratios chosen to study were 30, 50, and 80% with respect to the ...

The impact of gyrotactic microorganisms in the mixed convection stagnation point flow Cu-Al2O3/water hybrid nanofluid towards an immovable plate is numerically examined. boundary layer equation coupled with energy, nanoparticle volume fraction and conservation equations for are simplified into a set ordinary differential by adopting similarity transformation. validation results good agreement p...
