The Turbulent energy transfers are studied concurrently in physical and scale spaces in terms of the fully generalised Karman-Howarth equation which is valid without any restriction as it is just a two-point reformulation of the incompressible Navier-Stokes equations. Direct Numerical Simulations of two turbulent flows are considered: triply periodic turbulence, which serves to demonstrate significant correlations between different fluctuating transfer processes, and the planar turbulent near wake where a balance between interscale transfer rate and turbulence dissipation exists which has nothing to do with its Kolmogorov counterpart for homogeneous stationary turbulence and a lot to do with inhomogeneity and the presence of coherent structures.
The seminar is held at the Discovery Learning Center (DLC) at the University of Colorado. Parking is free with a permit, which is provided at the seminar. The location for parking is shown in the map below.Larger Map
