On the evolution of the velocity gradient tensor in transitional boundary layers
Ahmed Elnahhas, Perry L. Johnson, Adrián Lozano-Durán +1
We study the transition to turbulence from the perspective of the velocity gradient tensor dynamics. Our work is motivated by the observation of nonlinear structures emerging durin…

Energy transfer from large to small scales in turbulence by multi-scale nonlinear strain and vorticity interactions
Perry L. Johnson
An intrinsic feature of turbulent flows is an enhanced rate of mixing and kinetic energy dissipation due to the rapid generation of small-scale motions from large-scale excitation.…

Predicting the impact of particle-particle collisions on turbophoresis with a reduced number of computational particles
Perry L. Johnson
A common feature of wall-bounded turbulent particle-laden flows is enhanced particle concentrations in a thin layer near the wall due to a phenomenon known as turbophoresis. Even a…
