Analysis of melting heat transfer in MHD nanofluid flow with coupled reactions and thermal radiation

The present study examines the boundary layer flow and heat transfer of water-based nanofluid having silver and copper nanoparticles over a stretching sheet in the presence of melting heat transfer, thermal radiation, inclined magnetic field, heat generation and coupled chemical reactions. The results show that the magnetic field reduces fluid flow and enhances temperature distribution, while thermal radiation and heat generation increase the temperature. Increment of nanoparticle volume fraction, velocity decreases and temperature increases due to higher thermal conductivity. Species concentration decreased with increasing coupled reaction rates. Skin friction coefficient decreases ~15.5% as the ratio parameter is increased from 0 to 0.3. The increase of the magnetic parameter from 0 to 1.5 leads to an increase of the skin friction coefficient by 33% and decrease Nusselt number by 2%. The results provide guidance for the design of advanced thermal management systems, energy storage devices, and reactive transport technologies involving nanofluids.
