2 Introduction Turbulence cannot exist by itself, however; it requires a continuous supply of energy& changes in velocity& direction.
3 Objective The Definition of turbulence Examples of turbulence Boundary layer Study Reynolds numbers Study the differential continuity equation Study Navier-Stocks equation Kolmogorov theory Laminar-turbulent transition Problems of turbulence
4 Definition & properties It is a flow with disordered in time & space. 1-three-dimensionality. 2-Unsteadiness. 3-strong vorticity. 4-Unpredictability. 5-Broad spectrum.
26 Kolmogorov theory 1.The physics of turbulence is the same in all turbulent system. 2.It is independent of large scale forcing & small scale dissipative 3.Fluctuation occur in an incompressible medium-density 4.Energy flows from large scales to small scales.
