Overview

Numerical analysis reveals changes in drag coefficient and non-equilibrium dissipation behavior in turbulence, indicating significant spacing effects.

Key Points

  • The downstream tree's drag coefficient increases with distance between trees, suggesting an interesting spacing effect.
  • At 8H spacing, the region exhibiting non-equilibrium dissipation is notably shorter than at smaller spacings, revealing dynamic turbulence behavior.
  • Numerical simulations employed a cumulant lattice Boltzmann method to analyze turbulence statistics and dissipation effects.
  • Global and local isotropy assessments indicate that the wakes of paired fractal trees are approximately isotropic under specific flow conditions.
