Overview

Numerical investigation reveals heat transfer dynamics in rotating channels, suggesting improved designs for cooling systems.

Key Points

  • This research aims to understand how channel geometry and rotational speed affect heat transfer and flow characteristics in rotating channels.
  • Conducted three-dimensional numerical simulations using ANSYS Fluent.
  • Examined four different channel cross-sections: circular, elliptical, square, and rectangular.
  • Validated the numerical model against experimental data for circular channels.
  • Nusselt number generally increases with rotational speed, indicating enhanced heat transfer.
  • Friction factor increases with speed, impacting overall thermo-hydraulic efficiency.
  • Rectangular channels showed the highest thermal performance factor, reaching TPF of 1.09 at 500 rpm.
