Normality-based analysis of multiscale velocity gradients and energy transfer in direct and large-eddy simulations of isotropic turbulence
Rahul Arun, Mostafa Kamal, Tim Colonius +1
Symmetry-based analyses of multiscale velocity gradients highlight that strain self-amplification (SS) and vortex stretching (VS) drive forward energy transfer in turbulent flows.…
Velocity gradient partitioning in turbulent flows
Rahul Arun, Tim Colonius
The velocity gradient tensor can be decomposed into normal straining, pure shearing and rigid rotation tensors, each with distinct symmetry and normality properties. We partition t…
Velocity gradient analysis of a head-on vortex ring collision
Rahul Arun, Tim Colonius
We simulate the head-on collision between vortex rings with circulation Reynolds numbers of 4000 using an adaptive, multiresolution solver based on the lattice Green's function. Th…
Towards real-time reconstruction of velocity fluctuations in turbulent channel flow
Rahul Arun, H. Jane Bae, Beverley J. McKeon
We develop a framework for efficient streaming reconstructions of turbulent velocity fluctuations from limited sensor measurements with the goal of enabling real-time applications.…
