Question

Turbulence can be categorized as:

i. Homogeneous turbulence
ii. Isotropic turbulence
iii. Anisotropic turbulence
(a) i, ii, iii
(b) i, iii, ii
(c) ii, i, iii
(d) ii, iii, i

Answer 1

Turbulence is characterized by eddies and swirls which mix layers of fluid. It can be categorized as Isotropic, Homogeneous, and Anisotropic turbulence in that order. The correct sequence is Isotropic turbulence, Homogeneous turbulence, Anisotropic turbulence (c) ii, i, iii.

Step-by-step explanation:

Turbulence can be categorized into three types, which are:

Homogeneous turbulence: The statistical properties of the turbulence are the same at every point in space.

Isotropic turbulence: The statistical properties of the turbulence are the same in all directions. Hence, there is no preferred direction of flow or swirls.

Anisotropic turbulence: The statistical properties are not the same in all directions, meaning there is a preferred direction to the flow or distribution of eddies and swirls.

Therefore, the correct sequence for categorizing turbulence is (c) ii, i, iii – which is Isotropic turbulence, Homogeneous turbulence, Anisotropic turbulence.
