Isotropic turbulence occurs __________________?
Correct answer: A. Where there is no velocity gradient
- A. Where there is no velocity gradient
- B. At higher temperatures
- C. Only in Newtonian fluids
- D. None of these
Explanation
Isotropic turbulence has statistically equal properties in all directions and is associated in basic treatments with regions having negligible mean velocity gradients. Temperature and whether the fluid is Newtonian do not define isotropy.
