چکیده

The predictions of resolvent analysis with and without eddy viscosity are evaluated for a friction Reynolds number 550. low-rank behavior the standard identifies energetic regions flow whereas is low rank when resulting projection leading mode onto from spectral proper orthogonal decomposition maximum. energy dissipation transport that introduced by examined to explain success or failure resolvent.

Large-eddy simulation and wall modelling of turbulent channel flow

We report large-eddy simulation (LES) of turbulent channel flow. This LES neither resolves nor partially resolves the near-wall region. Instead, we develop a special near-wall subgrid-scale (SGS) model based on wall-parallel filtering and wall-normal averaging of the streamwise momentum equation, with an assumption of local inner scaling used to reduce the unsteady term. This gives an ordinary ...

Large-eddy Simulation of a Particle- Laden Turbulent Channel Flow

Large-eddy simulations of a vertical turbulent channel flow with 420,000 solid particles are performed in order to get insight into fundamental aspects of a riser flow. The question is addressed whether collisions between particles are important for the flow statistics. The turbulent channel flow corresponds to a particle volume fraction of 0.013 and a mass load ratio of 18, values that are rel...

Energetic Modes in Turbulent Pipe Flow From Resolvent Analysis

We describe a method to investigate the mode shapes in turbulent pipe flow at a given wavenumber pair that are most responsive to harmonic forcing in the sense that the they correspond to the largest singular value in a Schmidt decomposition of the linear NavierStokes operator using the turbulent mean profile as the base flow. The ideas follow logically from the work of Sharma & McKeon (2009), ...
