FUNCTIONAL REYNOLDS STRESS MODELING

  by Joan G. Moore and John Moore    

Cover Illustration - The World of Turbulence Glyphs

The isotropic sun rises over the field nourished by the 2-d lake. The Mohr's circle plow harvests 1-d potatoes in the shade of spectral trees. Shear flow paths wend through the woods and a satellite glyph provides internet communications. The illustration is a collage from Figs. 1.2.1, 1.2.2, 1.2.5 and 17.6.5.

Identify the pieces

Reynolds stress tensor glyphs -

  • for isotropic turbulence
  • for 2-d turbulence (one principal normal stress is zero)
  • for 1-d turbulence (only one principal normal stress is not zero)
  • 3-d turbulence
