Coherent Streamwise Vortex Structure of a Three-Dimensional Wall Jet
Fluids, 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).

SIMULATION OF TURBULENCE AS A «VORTEX BACKFILL»
Известия 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
Nihon 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

Turbulence Structure in Plane Turbulent Couette Flow.
TRANSACTIONS 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 ...

The structure of turbulent shear flow [PDF]
Journal of the Franklin Institute, 1956 A theoretical investigation is made of the mixing layer between two streams. The work is divided into four sections. The first involves the solution of the mean problem of laminar and turbulent mixing. The equations of motion are written in terms of a similarity variable. An eddy viscosity hypothesis is made to describe the shear stresses.

Mechanisms of turbulent flame propagation [PDF]
, 1978 Measurements are reported of premixed hydrogen-air turbulent burning velocities, made by the double kernel method during explosions. Turbulence was created by four high speed fans driven by electric motors within the explosion vessel.

Turbulent bubbly flow in pipe under gravity and microgravity conditions [PDF]
, 2012 Experiments on vertical turbulent flow with millimetric bubbles, under three gravity conditions, upward, downward and microgravity flows (1g, -1g and 0g), have been performed to understand the influence of gravity upon the flow structure and the phase ...

Multifractal Model of Atmospheric Turbulence Applied to Elastic Lidar Data
Atmosphere, 2021 This paper shall present a multifractal interpretation of turbulent atmospheric entities, considering them a complex system whose dynamics are manifested on continuous yet non-differentiable multifractal curves.
