description: Recent advancements in nanotechnology have led to significant improvements in the design, manufacturing, and thermal efficiency of engineering systems. Nanofluids, when combined with extended surfaces, enhance heat transfer performance, helping to prevent overheating while also offering improved stability, durability, and adaptability across various environmental conditions. This research focuses on the thermal response of a moving porous fin featuring a concave parabolic profile, immersed in a nanofluid composed of water as the base fluid and molybdenum disulfide (MoS2) nanoparticles. The governing nonlinear nanofluid model is nondimensionalized, and thermal characteristics such as temperature profiles, heat transfer rates, efficiency, and fin effectiveness are obtained using the Homotopy Perturbation Method (HPM). The effects of important dimensionless parameters on thermal profiles are examined through graphical illustrations. The results demonstrate that temperature rises with increases in the Peclet number and thermal conductivity, whereas it decreases as porosity, radiation, convection, and emissivity parameters increase. Furthermore, the inclusion of MoS2 nanofluid leads to an average heat transfer enhancement of approximately 3.84% compared to conventional fluids under radiative conditions. 2025
