Geometry Dynamics of Compressible Turbulence Structures
Abstract
This research pursues the characterization of the time-evolution of the geometry of finite-sized structures educed from turbulent flows. The objective is to provide a systematic, quantitative description of turbulence dynamics that relates the geometry of structures found at different scales, as evolved by the underlying turbulent flow, with the transported physical quantities on those structures. The analysis focuses on numerical simulation (DNS and LES) datasets of four canonical types of compressible turbulent flows: homogeneous isotropic turbulence (HIT), shear mixing layer, shearless mixing layer, and shock-turbulence interaction (STI). These flowtypes are chosen as they isolate several key characteristics of turbulence (convective nonlinearities, shear and acoustic-vorticity coupling, anisotropy, and rapid compression/distortion).
