Comparative Analysis of Al2O3/Water–TiO2/Chlorophyll Hybrid Nanofluids in a Photovoltaic–Thermal Solar Water Heating System

open access: yesEnergy Science &Engineering, EarlyView.
TiO2/chlorophyll bio‐hybrid nanofluid achieved the highest PVT performance, increasing thermal efficiency to 38.74% and overall efficiency to 51.35%, compared with 35.96% and 48.45% for Al2O3/water and 27.77% and 40.18% for water. The results demonstrate the potential of bio‐hybrid nanofluids for high‐efficiency solar thermal energy conversion ...

Numerical Study of Laminar Forced Convection of Nanofluid in a New Microchannel Heat Sink

open access: yesJournal of Mechanical Engineering, 2021
The heat transfer and pressure drop in a microchannel heat sink with 02 mixing chambers with inclined walls were numerically studied. The transport equations have been resolved by the finite volume method using ANSYS Fluent software. The operating fluids

Refinement of Nusselt numbers in drying processes

open access: yesMathematical Modeling and Computing
It is proposed to refine the calculation of Nusselt numbers by considering the mass transfer coefficient in the evaporation zone, which is significantly larger than the molecular mass transfer coefficient of vapour. This refinement aims to address the discrepancy between the elevated Nusselt criteria observed during drying and the criteria determined ...

Convergence and Residual Error Analysis of Unsteady MHD Stagnation Flow Over a Cylindrical Surface With Streamline and Isotherm Visualization

open access: yesEnergy Science &Engineering, EarlyView.
The novelty of the current study is that the unsteady MHD Cross nanofluid model is, for the first time, coupled with the melting heat transfer at the stagnation point over a horizontally extended cylinder in a Darcy–Forchheimer porous medium. This work connects complex rheological behaviors and phase‐change phenomena in a unique way, with the only ...

Radial boundary layer structure and Nusselt number in Rayleigh–Bénard convection [PDF]

open access: yesJournal of Fluid Mechanics, 2010
Results from direct numerical simulation (DNS) for three-dimensional Rayleigh–Bénard convection in a cylindrical cell of aspect ratio 1/2 and Prandtl number Pr=0.7 are presented. They span five decades of Rayleigh number Ra from 2 × 106 to 2 × 1011. The results are in good agreement with the experimental data of Niemela et al. (Nature, vol.

An Experimental Study of Thermal Energy Storage With Phase‐Change Material in a Rectangular Box Filled With Aluminum Foam

open access: yesEnergy Science &Engineering, EarlyView.
We experimentally evaluate a rectangular latent‐heat thermal energy storage box filled with paraffin RT57. Embedding 1–3 aluminum‐foam pieces (ε ≈ 0.89 and 10 PPI) increases effective thermal conductivity, making the temperature field more uniform and accelerating phase change.

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.
