Which outcome decreases stability in a laminar boundary layer subject to increased free stream turbulence?

💡 Explanation

Increased free stream turbulence triggers enhanced momentum diffusion because it decreases fluid dynamic viscosity via increased random molecular motion; therefore enhanced mixing accelerates instability growth, rather than delaying transition since viscosity is lowered.
