Effects of Concentrations of Water‐Based MgO Nanofluid on Heat Transfer Performance in Shell‐and‐Tube Heat Exchanger

Energy Science &Engineering, EarlyView.
This figure shows the variation of the total heat transfer coefficient of a shell and tube heat exchanger with different concentrations of water‐based MgO nanofluids at different inlet flow rates. The results indicate that the total heat transfer coefficient increases with increasing flow velocity, and at different volume fraction settings, the ...

Numerical Simulation and Analysis of Heat Transfer Characteristics in Gradient‐Porosity Foam Copper Composite Phase Change Materials

Energy Science &Engineering, EarlyView.
This study investigates the heat transfer characteristics of copper‐foam composite phase change materials with different gradient porosities. Three models with uniform porosity and three models with gradient porosities are developed to examine their effects on temperature distribution and melting behavior. ABSTRACT Phase change materials (PCMs) exhibit

Downdraft Devices for Negative Emissions—Quantification Study and Environmental Implication

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Methane (CH4) is a potent greenhouse gas with a global warming potential far exceeding that of CO2 over short time horizons. Its removal from the atmosphere remains challenging due to its low ambient concentration and chemical stability. This study explores downdraft energy towers (DETs) as an innovative CH4 mitigation technology that enhances

Direct Numerical Simulation of Magnetohydrodynamic Slip‐Flow Past a Stretching Surface Using Physics‐Informed Neural Network

Heat Transfer, EarlyView.
ABSTRACT Traditional numerical methods, such as finite difference methods (FDM), finite element methods (FEM), and spectral methods, often face meshing challenges and high computational cost for solving nonlinear coupled differential equations. Machine learning techniques, specifically Physics‐informed machine learning, address these obstacles by ...

CFD Analysis of Dual‐Layer PCM Roofs for Thermal Mitigation in Residential Buildings

Heat Transfer, EarlyView.
ABSTRACT This study presents a computational fluid dynamics analysis of dual‐layer phase change material (PCM) roofs for passive cooling in residential buildings under the hot and humid climate of Bangladesh. A three‐dimensional transient model was developed in ANSYS Fluent using the enthalpy–porosity approach to simulate coupled heat conduction ...

Enhanced Dichroic Coloration Through Void‐Particle Induced Interference in Randomly Distributed Cu2O Octahedrons on Glass Substrate

Laser &Photonics Reviews, EarlyView.
In randomly distributed Cu2O octahedron particles on a glass substrate, the absence of particles in certain areas generates a distinct “void‐particle induced interference” phenomenon. This effect results in notable reflection and transmission dichroism, characterized by two reflection peaks within the visible spectrum, but only a single transmission ...
