The aerodynamic drag of a tree

This folder contains pages that concern the aerodynamic modeling of leafless trees. This is part of a bigger research project named Plantenna.

Simulations

• Flow past a 2D cylindrical branch
• Flow past two 2D cylindrical branches
• A rapidly growing tree
• Flow past a 3D cylindrical branch
• Flow past a fractal tree
• Flow past a space-colonized tree
• (some increasingly complex pages)
  
• Flow past realistic tree geometries

Cell-fraction embedded-tree pages

• A Simple fractal
  
• A tree generated with space colonization
  
• A “real tree” from line-segment skeleton (via QSMTREE)
  
• A “real tree” from a .stl file (via Adtree)

Methods

• Generate a fractal tree and volume fractions from line-segment skeleton
• Minimal example of \Delta \propto R^{-0.5} with adapt_wavelet()
• Example of \Delta R^{-1} = c \times Re^{-0.5} on 3 branches
• Frontal area of a fractal tree
• Space colonization

Miscellaneous pages

• A model for a growing plant root
• Write “Plantenna” with a growing plant-root font
