Abstract

This study explores free convective heat transfer in an electrically conducting nanofluid flow over a moving semi-infinite flat plate under the influence of an induced magnetic field and viscous dissipation. The velocity and magnetic field vectors are aligned at a distance from the plate. The Spectral Relaxation Method (SRM) is used to numerically solve the coupled nonlinear partial differential equations, analyzing the effects of the Eckert number on heat and mass transfer. Various nanofluids containing , , , and nanoparticles are examined to assess how external magnetic fields influence fluid behavior. Key parameters, including the nanoparticle volume fraction , magnetic parameter , magnetic Prandtl number , and Eckert number , are evaluated for their impact on velocity, induced magnetic field, and heat transfer. Results indicate that increasing the magnetic parameter reduces velocity and magnetic field components in alumina-water nanofluids, while a higher nanoparticle volume fraction enhances the thermal boundary layer. Greater viscous dissipation increases temperature, and nanofluids exhibit higher speeds than , , and due to density differences. Silver-water nanofluids, with their higher density, move more slowly. The SRM results closely align with those from Maple, confirming the method’s accuracy.
