Destratification of thermally stratified turbulent open-channel flow by surface cooling

On Coherent Structures of Turbulent Open-channel Flow Above a Rough Bed

Present study examines turbulent structures of a rough bed open-channel flow in the context of deterministic approach. Instantaneous velocity field is measured in different hydraulic conditions using two dimensional Particle Image Velocimetry (PIV) in vertical plane and Stereoscopic PIV in horizontal plane. Different techniques and quantities such as swirl strength, two-point and cross-correlat...

Application of Renormalization Group Method in Thermally Stratified Turbulent Flows

Renormalization group theory is applied to stratified turbulence. Various results due to nonlinearities, buoyancy and reference temperature gradient So are reported for cases where (Sol ts untform and sufficiently large. The main result is that the imposition of strong stratification leads to a new renormalization group fixed point and a (-3) law for the

Large eddy simulation of stably stratified open channel flow

Turbulent oscillating channel flow subjected to a free-surface stress

The channel flow subjected to a wind stress at the free surface and an oscillating pressure gradient is investigated using large-eddy simulations. The orientation of the surface stress is parallel with the oscillating pressure gradient and a purely pulsating mean flow develops. The Reynolds number is typically Re!=10 and the Keulegan–Carpenter number—the ratio between the oscillation period and...
