The various fluid parcels come into contact in turbulent flow by _____

1.	The various fluid parcels come into contact in turbulent flow by ___________(a) Turbulent energy transfer(b) Turbulent vorticity(c) Turbulent dissipation(d) Turbulent diffusionThis question was posed to me in my homework.I want to ask this question from Turbulence Modelling topic in division Turbulence Modelling of Computational Fluid Dynamics
Answer» Correct option is (d) TURBULENT DIFFUSION Explanation: Turbulence INCREASES the RATE at which conserved quantities are mixed. Here, different fluid PARCELS are brought into contact. As this mixing is accomplished by diffusion, the process is called turbulent diffusion.
