Which risk increases when turbulent kinetic energy overwhelms dissipation?

💡 Explanation

An increase in turbulent kinetic energy causes increased boundary layer separation because fluctuations in pressure lead to reversed flow according to the Reynolds-averaged Navier-Stokes equations. Therefore, flow separation increases rather than decreased drag since turbulence promotes momentum transfer.
