Overview

Numerical investigation models turbulent flow in channels, highlighting effects of surface roughness on friction and heat transfer.

Key Points

  • This study investigates how surface roughness affects turbulent flow dynamics in channels, particularly focusing on aerodynamics and heat transfer.
  • Numerical simulations were performed using the k-ε turbulence model in Comsol Multiphysics 6.2.
  • Calculations were conducted across various roughness heights to represent smooth, transitional, and fully rough flow regimes.
  • Analysis included velocity profile, friction coefficient, and Stanton number, compared with experimental data.
  • The k-ε model showed satisfactory agreement for friction and heat transfer characteristics across different flow regimes.
  • Discrepancies were noted near the wall and in transitional flow regions.
