Phase change heat transfer in a square enclosure containing a power-law nanofluid and a circular cylinder at various vertical positions

Key Points

• Phase change heat transfer improves with optimal positioning of the circular cylinder in the enclosure.
• Fluid behavior measured through power-law nanofluid demonstrates enhanced thermal conductivity characteristics.
• Assessment using computational fluid dynamics methods reveals variations in heat transfer efficiency across vertical cylinder positions.
• These findings may enable optimized designs for thermal management systems in engineering applications.
