Q: Is turbulence commonly observed in everyday phenomena such as surf? ¶
A: Yes, and fast flowing rivers, billowing storm clouds, or smoke from a chimney, and most fluid flows occurring in nature and created in engineering applications are turbulent.
Q: Was turbulence that a turbulent flow is composed by "eddies" of different sizes? ¶
Q: Is turbulence generally interspersed with laminar flow until a larger Reynolds number of about 4000? ¶
Q: Is turbulence caused by excessive kinetic energy in parts of a fluid flow? ¶
A: Yes, and which overcomes the damping effect of the fluid's viscosity.
Q: Is turbulence dominated by the coherent structure activities and associated turbulent events? ¶
Q: Is turbulence statistically self-similar at different scales? ¶
Q: Is turbulence easier to create in low viscosity fluids? ¶
A: Yes, but more difficult in highly viscous fluids.
Q: Is turbulence to understand what is really universal in the inertial range? ¶
Q: Is turbulence always rotational and three dimensional? ¶
