Turbulence FAQs:


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?

A: Yes.

Q: Is turbulence generally interspersed with laminar flow until a larger Reynolds number of about 4000?

A: Yes.

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?

A: Yes.

Q: Is turbulence statistically self-similar at different scales?

A: Yes.

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?

A: Yes.

Q: Is turbulence always rotational and three dimensional?

A: Yes.
