First Course In Turbulence Solution Manual Exclusive: A

The allure of the solution manual is obvious: Turbulence is hard. The subject involves statistical tools, correlation tensors, and the infamous "closure problem." When stuck on a derivation involving the Kolmogorov microscales or the energy cascade, seeing the solution provides a lifeline.

However, reliance on the manual carries a significant risk. The educational value of Tennekes and Lumley lies in the struggle of the derivation.

If you are a student reading this, you are likely torn. You have three assignments due, a midterm next week, and you are stuck on problem 4.7 involving the Lagrangian autocorrelation function. Should you hunt for the exclusive solution manual?

In wind-tunnel turbulence behind a grid, TKE decays as ( k \sim x^-n ). Given ( dk/dt = -\varepsilon ) and ( \varepsilon \sim k^3/2/L ), with ( L ) constant, find ( n ).

Solution:
( dk/dt = U dk/dx = -C k^3/2/L ). Separate variables: ( k^-3/2 dk = -(C/(UL)) dx ). Integrate: ( -2 k^-1/2 = -(C/(UL)) x + \textconst ). Thus ( k^1/2 \sim x^-1 ), so ( k \sim x^-2 ), i.e., ( n=2 ). (Tennekes & Lumley give ( n \approx 1.25 ) in real flows due to ( L ) increasing slightly.)
