Effect of the Inlet Boundary Conditions on the Flow over Complex Terrain Using Large Eddy Simulation
For large eddy simulation, it is critical to choose the suitable turbulent inlet boundary condition as it significantly affects the calculated flow field.

Simulation of Three-Dimensional Flow Field around Unconventional Bridge Piers [PDF]
The study presents a three-dimensional numerical simulation of turbulent flow field around unconventional bridge piers which are downstream-facing round- nosed (DS-FRNP) and upstream- facing round- nosed (US-FRNP) and are compared with a circular pier in

Velocity distribution and hydrodynamic drag in turbulent flow [PDF]
This work aims to study the vertical velocity distribution in the near-wall layer of a pipe, channel, and boundary layer of a flat plate because these issues are of great practical and theoretical importance.

Modification of energetic modes for transitional flow control
We introduce a mechanism of using collocated serpentine shaped plasma actuators for controlling the flow via an input electrical signal to either advance or delay transition by amplification or annihilation of energetic modes of turbulent structures.

Transitions of turbulent superstructures in generalized Kolmogorov flow
Self-organized large-scale flow structures occur in a wide range of turbulent flows. Yet, their emergence, dynamics, and interplay with small-scale turbulence are not well understood.

Model-based design of transverse wall oscillations for turbulent drag reduction
Over the last two decades, both experiments and simulations have demonstrated that transverse wall oscillations with properly selected amplitude and frequency can reduce turbulent drag by as much as 40%.

Turbulent energy motion of fiber suspensions in a rotating frame
Turbulent flows play a major role in many fields of science and industry. Noticeable attention is seen on turbulent flows of suspending fibers because of the sensitivity of the electrical, thermal, and mechanical properties of the connecting fiber ...
