Overview

Experimental and numerical analysis reveals that surface roughness and pulsations enhance heat transfer in pipes, indicating the impact of turbulence and thermal boundary layer disruption.

Key Points

  • Surface roughness significantly enhances heat transfer by increasing turbulence and disrupting the thermal boundary layer.
  • Introducing flow pulsations can further improve heat transfer performance, with downstream pulsation increasing Nusselt number by 20-22%.
  • Reynolds number plays a crucial role in establishing the relationship between turbulence intensity and heat transfer coefficients.
  • A combination of controlled flow pulsations and surface roughness offers potential for optimizing thermal systems in industrial environments.
