Overview

This multiphysics modeling study optimizes bimetallic nano-ellipsoids for enhanced solar energy absorption.

Key Points

  • The study aims to optimize bimetallic Au@Pt nano-ellipsoids to improve solar thermal harvesting efficiency under low concentration.
  • Designed and optimized bimetallic Ag@Pt and Au@Pt nano-ellipsoids as advanced nano-heaters.
  • Utilized a 3-D computational modeling framework using finite element method for optical absorption properties.
  • Calculated solar-weighted absorption coefficients to evaluate nanofluid performance in direct absorption solar collectors.
  • Achieved a solar-weighted absorption efficiency exceeding 99% at a concentration of 2.0 × 10−7.
  • Improved uniform temperature distribution by approximately 15% compared to spherical nanoparticles.
  • Demonstrated superior absorption performance of optimized nano-ellipsoids over conventional nanofluids.
