Transfer of kinetic energy from large eddies to smaller eddies is call

1.	Transfer of kinetic energy from large eddies to smaller eddies is called as _________(a) Energy cascade(b) Momentum cascade(c) Energy decomposition(d) Momentum decompositionI have been asked this question during a job interview.The question is from Turbulence Modelling topic in division Turbulence Modelling of Computational Fluid Dynamics
Answer» Correct choice is (a) ENERGY cascade The BEST explanation: Smaller eddies are stretched STRONGLY by large eddies. THEREBY, KINETIC energy is transferred from larger eddies to smaller and smaller eddies. This is called energy cascade.
