Scale-space dynamics of homogeneous turbulence
Illinois Institute of Technology
Abstract
The scale-space framework was originally and infamously used by A. Kolmogorov in 1941 to derive theoretical predictions for the distribution of kinetic energy in homogeneous turbulent flows. Over eighty years later, the scale-space framework continues to bear fruit on this fascinating and challenging topic. In this talk, the instantaneous dynamics that govern the overall cascade of energy and helicity are presented within the scale-space framework, and new insights based on the Lamb decomposition are provided. The mechanics of turbulence energy transfer and how new insights can be translated into useful engineering knowledge will be discussed.
About the speaker
Dr. Douglas W. Carter is an Assistant Professor in the Department of Mechanical, Materials and Aerospace Engineering at the Illinois Institute of Technology. He earned his bachelor’s degree in mechanical engineering from the University of New Hampshire in 2014 and his master’s and Ph.D. in aerospace engineering and mechanics from the University of Minnesota in 2017 and 2019, respectively. He held two postdoctoral positions, one at the University of Southampton (UK) and one at Sandia National Laboratories before he was appointed to his current role at Illinois Tech in August of 2024. His research interests encompass all experimental turbulent flows with recent emphasis on high-speed facilities and laser-based diagnostics.
