Small-scale eddy motions have ___________(a) does not vary from the energy losses of the large-scale eddy motions(b) the same order of energy losses as the large-scale eddy motions(c) decreased energy losses(d) increased energy lossesI got this question in unit test.I'm obligated to ask this question of Turbulence Modelling in division Turbulence Modelling of Computational Fluid Dynamics

Answer»

Correct OPTION is (d) increased energy losses

For EXPLANATION I WOULD say: Small-scale eddy motions are dissipative. The energy associated with these motions is converted into thermal internal energy. This leads to increased energy losses associated with the TURBULENT flows.
