A mechanism for the generation of turbulence and related phenomena in dissipative systems is proposed.
On the transient nature of localized pipe flow turbulence The onset of shear flow turbulence is characterized by turbulent patches\nbounded by regions of laminar flow. At low Reynolds numbers localized\nturbulence relaminarises, raising the question of whether it is transient in\nnature or it b....

On the Possibility of the Cahn-Hilliard Approach Extension to the Solution of Gas Dynamics Problems (Inner Turbulence) We consider the truncated Euler system and analyze bifurcations of a one-front solution to a solution with two fronts. In particular, it is shown that ... EA Lukashev,NN Yak...
An experimental study was performed to further the understanding of turbulent mixing in a two-layer fluid subjected to shear-free turbulence. At low Richardson numbers Ri(=Delta bD* 3/ K2, where Delta b is the buoyancy jump, D* is the depth of a mixed layer and K is `action') the ...
A leading economist uses a historical lens to gain insights into the economic consequences of pandemics, likely trends in wealth and globalization, and whether current economic turbulence signals the start of a new era. In this episodeof the McKinsey Glo...
Particle image velocimetry (PIV) is a well-established tool to collect high-resolution velocity and turbulence data in the laboratory, in both air and water. Laboratory experiments are often performed under conditions of constant temperature or salinity or in flows with only small gradients of these...
The issue is about turbulence as a natural physical phenomenon as related to observations as distinct from the problem of turbulence. The dichotomic distinction between laminar and turbulent flows is problematic in several respects. First, most flows termed "turbulent" are in reality partly turbulent:...
