Overview

This analysis investigates heat transfer in nanofluid flow over rotating inclined disks, suggesting shape modifications improve efficiency.

Key Points

  • The aim is to analyze how different nanoparticle shapes affect heat transfer in nanofluid flow over inclined disks.
  • Investigated five shapes of nanoparticles, each 45 nm in diameter, suspended in a fluid.
  • Applied a similarity transformation to convert nonlinear PDEs to ODEs.
  • Utilized the differential transform method to solve the ODEs.
  • Considered effects of joule heating and viscous dissipation on heat transfer.
  • Increased porosity raised the temperature of the nanofluid due to enhanced viscous dissipation.
  • The skin friction coefficient decreased by 10%-15% when the volume fraction increased from 0% to 5%.
  • Including thermal radiation significantly improved the heat transfer performance.
