ABSTRACT Thermal management systems integrating phase change materials face challenges in maximizing heat transfer efficiency for electronics cooling and energy storage applications. This study addresses the research gap regarding fluid‐structure interaction magnetohydrodynamic effects on nano‐encapsulated PCM performance complex geometries. We investigate thermal transport a curvilinear enclosure containing NEPCM with an oscillating lower boundary two cold cylinders under electromagnetic field influence. Using finite element methodology specialized treatment moving boundaries, we evaluate key parameters: Rayleigh number ( Ra : 10³–10⁵), Stefan (Ste: 0.1–0.9), transition temperature θ f concentration ϕ 0.01–0.04), oscillation amplitude A 0.01–0.15), Hartmann Ha 0–20), magnetic angle γ 0°–90°). Results reveal that increasing from 10³ to 10⁵ enhances by 122.9%, while nanoparticle addition improves 37% as increases 0.01 0.04. The inhibits transfer, Nu decreasing 25.9% 0 20. These findings provide design guidelines applications electromagnetically active environments.
