Comparative Analysis of Graded‐Index and Quarter‐Wave One‐Dimensional Photonic Crystal Filters for GaSb Thermophotovoltaic Cells

Energy Technology, EarlyView.
The efficiency and output power of thermophotovoltaic systems can be improved by using one‐dimensional photonic crystal optical filters with graded index profiles. Using a filter with a graded index profile increases the system efficiency from 15.8 to 27%.

Evaluation of the Impact of Incident Wavefield Modeling on Soil‐Structure Interaction of Buildings Using Broadband Physics‐Based 3D Earthquake Simulations

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Despite the complexity of real earthquake motions, the incident wavefield excitation for soil‐structure interaction (SSI) analysis is conventionally derived from one‐dimensional site response analysis (1D SRA), resulting in idealized, decoupled vertically incident shear and compressional waves for the horizontal and vertical components of the ...

Solar Energy Storage Optimization Using Fractional Derivative Simulations of Maxwell Hybrid Nanofluid Flow: Entropy Generation Analysis

Energy Science &Engineering, EarlyView.
ABSTRACT This attempt examines the heat transfer enhancement from unsteady bioconvective Maxwell nanofluid flow under the incidence of solar radiation influenced by viscous dissipation and chemical reaction through a porous medium. The nanofluid contains silver and titanium alloy hybrid nanoparticles with gyrotactic micro‐organisms in ethylene glycol ...
