The current work investigates experimental characteristics of the PVT system integrated with CuO-water spiral flow heat exchanger and compared non-cooled PV module. describes detailed procedure nanoparticles preparation, SEM characterizations, extraction nanofluid in application. was pasted at back polycrystalline module to form examine cooling ability, power generation, thermal-electrical yiel...

In this article, the instable fluid velocity in the pipes with internal nanofluid is studied. The fluid is mixed by SiO2, AL2O3, CuO and TiO2 nanoparticles in which the equivalent characteristic of nanofluid is calculated by rule of mixture. The force induced by the nanofluid is assumed in radial direction and is obtained by Navier-Stokes equation considering viscosity of nanofluid. The displac...

For the first time, a facile, one-pot water/ethanol solution-phase transformation of Cu2(NO3)(OH)3 precursors into bicomponent CuO hierarchical nanoflowers is demonstrated by a sequential in situ dissolution-precipitation formation mechanism. The first stage produces a precursory crystal (monoclinic Cu2(NO3)(OH)3) that is transformed into monoclinic CuO nanoflowers during the following stage. W...

In this study, the effects of microchannel number, volume concentration, Reynolds and nanofluid type on heat transfer flow characteristics in sink consisting trapezoidal microchannels are investigated numerically. Governing equations solved by assuming three-dimensional, incompressible, steady laminar flow. The channel material is chosen as copper, a constant flux boundary condition defined upp...

The advancement of heat transfer techniques is a challenge to the researcher in this era. Implementation nanotechnology one potential which enhance rate significant amount. Subsequently, can reduce requirement pumping power. However, suspension nanoparticle with liquid produce new working fluid called nanofluid has better thermal and dynamic properties comparison

Abstract This paper presents an effort to model the process parameters involved in turning of alloy steel AISI 4340 workpiece material with Al 2 O 3 and CuO hybrid nanofluids using minimum quantity lubrication (MQL) method. In this paper, effect mixing two nanoparticles (Al CuO) different weight percent environmentally friendly water-based cutting fluid, rotational speed, feed rate has been inv...

In this work, a Homotopy Perturbation Solution of magnetohydrodynamic (MHD) model of boundary-layer equations for an electrically conducting Nanofluid flow bounded by an infinite parallel vertical permeable plates is to be introduced. This model is applied to study the mass and heat transfer of an unsteady nanofluid, incompressible flow with suction, internal heat generation, Hall Effect and Ch...
