Overview

Randomized trial investigates boiling effects on turbulent flow characteristics in liquid hydrogen, indicating significant phase change interactions.

Key Points

  • This study aims to explore the effects of wall boiling on the turbulence of liquid hydrogen in a parallel-plate channel.
  • Conducted direct numerical simulations of turbulent liquid hydrogen.
  • Analyzed turbulence statistics and phase change interactions near the wall.
  • Examined effects of wall heating on turbulence structure and boiling phenomena.
  • Boiling increased wall-normal and spanwise velocities, boosting turbulent kinetic energy by approximately 1.5 times.
  • Turbulence initially enhanced phase change at the wall, followed by a gradual suppression.
  • Boiling modulated wall turbulence towards isotropy, affecting the local flow dynamics.
