ABSTRACT This study investigates double‐diffusive transport and entropy generation in a wavy cylindrical enclosure containing Cu─H 2 O Casson nanofluid under magnetic field thermal radiation effects. The governing equations were solved numerically using the finite element method with Galerkin formulation. investigation covered parametric ranges including Rayleigh number (10³ ≤ Ra 10⁶), Hartmann (0 Ha 40), inclination (0° γ 90°), nanoparticle volume fraction φ 0.15), parameter (0.1 η 1), Rd 4), conductivity λ Lewis (0.5 Le 5), buoyancy ratio (0.25 Nz 1.5). Results demonstrated that increasing from 10³ to 10⁶ enhanced heat transfer by 60%, while 40 reduced fluid circulation 75%. significantly influenced flow characteristics, stream function values 75% as approached Newtonian behavior. Thermal parameters jointly moderated temperature gradients, causing 15%–20% reduction stratification. showed strong coupled effects, Sherwood 150% increased 0.5 5. These findings have practical applications advanced exchanger design, energy storage systems, electronic cooling technologies, biomedical devices, where controlled mass of non‐Newtonian fluids is crucial.
