A Delayed Detached Eddy Simulation Model for the Simulation of Complex Turbulent Flow [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2022
A new turbulent model based on Delayed Detached Eddy Simulation (DDES) with non-linear eddy viscosity model (NLEVM) was developed to predict the complex turbulent flow.

Turbulence Structure in Plane Turbulent Couette Flow.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1994
Turbulence structure in a fully developed turbulent plane Couette flow is studied experimentally at Reb=2×104. Turbulence structure in the wall region is similar to that in the two-dimensional channel flow. In the core region, however, turbulence structure is very different from that in the channel flow case because of uniform shear existing there ...

Coherent Streamwise Vortex Structure of a Three-Dimensional Wall Jet

open access: yesFluids, 2021
The dynamics of the coherent structures in a turbulent three-dimensional wall jet with an exit Reynolds number of 250,000 were investigated using the Snapshot Proper Orthogonal Decomposition (POD).

Experimental investigation of turbulent flows around high-rise structure foundations and implications on scour

open access: yesWater Science and Engineering, 2022
Many studies have been undertaken to predict local scour around offshore high-rise structure foundations (HRSFs), which have been used in constructing the Donghai Wind Farm in China.

Modelling the dynamics of turbulent floods [PDF]

open access: yes, 2002
Consider the dynamics of turbulent flow in rivers, estuaries and floods. Based on the widely used k-epsilon model for turbulence, we use the techniques of centre manifold theory to derive dynamical models for the evolution of the water depth and of ...

SIMULATION OF TURBULENCE AS A «VORTEX BACKFILL»

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2018
The new method of simulation and the turbulent flow research, based on representation about turbulence as a current through «vortex backfill» is offered. The method of local fluctuations offered earlier is applied to its realization.

DNS of turbulent heat transfer in pulsating channel flow

open access: yesNihon Kikai Gakkai ronbunshu, 2020
A pulsating turbulent channel flow at constant wall temperature difference condition is studied by direct numerical simulation (DNS) to clarify the effect of pulsation frequency on turbulence statistics and heat transfer. The flow pulsation was forced to

Flow structure and optical beam propagation in high-Reynolds-number gas-phase shear layers and jets [PDF]

open access: yes, 2001
We report on the structure of the scalar index-of-refraction field generated by turbulent, gas-phase, incompressible and compressible shear layers and incompressible jets, and on associated beam-propagation aero-optical phenomena.
