A model based on a convolutional neural network (CNN) is designed to reconstruct the three-
dimensional turbulent flows beneath a free surface using surface measurements, including …

Turbulent drag reduction (DR) through streamwise travelling waves of the spanwise wall
oscillation is investigated over a wide range of Reynolds numbers. Here, in Part 1, wall …

Compressible turbulent plane Couette flows are studied via direct numerical simulation for
wall Reynolds numbers up to, the amplitude modulation of these structures on the near-wall …

In this work, we perform direct numerical simulations of Rayleigh–Bénard convection in a
two-dimensional confined square cell for Rayleigh numbers (Ra) from 10 9 to 10 13 and a …

Large amounts of small inertial particles embedded in a turbulent flow are known to modify
the turbulent statistics and structures, a phenomenon referred to as turbulence modulation …

The dynamics of turbulent kinetic energy (TKE), turbulence dissipation rate (TDR) and
turbulence production rate (TPR) are explored in fully developed turbulent channel flow …

We present a mixing length-based algebraic turbulence model calibrated to pipe flow; the
main purpose of the model is to capture the increasing turbulence production-to-dissipation …

Pore-resolved direct numerical simulations have been performed to investigate the turbulent
open-channel flow over a rough and permeable sediment bed, represented by a mono …
