| Research Abstract |
Interfaces between strongly turbulent and almost non-turbulent regions often appear in flows in nature and technology. Such interfaces are called here turbulent-nonturbulent(T-NT) interfaces. We have studied T-NT interfaces within turbulent flows with particular attention to the flow structure, energy transfer and material transport near the interfaces. By applying the method of conditional statistical analysis to the data of direct numerical simulations with the number of grid points up to the cube of 4096, we have revealed some characteristic features of the structure and energy transfer.
