Purpose This study aims to present a numerical investigation of the thin film thermal coating process using an electromagnetic Williamson ternary hybrid nanofluid (THNF), including (MWCNT [multi-walled carbon nanotubes] + SiO 2 [silicon dioxide] MoS [molybdenum disulfide]) materials, incorporating nanoparticle radius and interparticle spacing effects. Design/methodology/approach The control volume finite element method (CVFEM) is used for high-accuracy analysis. homotopy analysis (HAM) also applied obtain series solution transform system equations. effects fraction, radius, spacing, Eckert number interactions are main features this model. Findings increasing fraction significantly improves heat transfer. At 5% THNF achieves 18.072% increase, reaches 15.576% single-component MWCNT by 11.665%.Ternary hybrids observed ideal cooling applications, energy storage industrial exchangers. Through sensitivity analysis, it detected that model problem’s stability mainly dependent on thickness. Originality/value Thin over cylinder fluid novel contribution. combination MWCNT, nanomaterials results in coating, which new addition. Nanoparticle essential tiny layer considered study. Electromagnetic effect, radiation, convection, porous medium variable thickness other two methods Control Volume Finite Element Method (CVFEM), Homotopy Analysis
