COUNTER-ROTATION IN RELATIVISTIC MAGNETOHYDRODYNAMIC JETS [PDF]
The Astrophysical Journal, 2014 Young stellar object observations suggest that some jets rotate in the opposite direction with respect to their disk. In a recent study, Sauty et al. (2012) have shown that this does not contradict the magnetocentrifugal mechanism that is believed to launch such outflows.

Design procedure for a wind-wheel with self-adjusting blade mechanism
Trudy Odesskogo Politehničeskogo Universiteta, 2014 Developed is a wind-wheel design equipped with the self-adjusting blade. The blade is positioned eccentrically to the balance wheel and can freely rotate around its axis. Elaborated is the method of calculating the energy characteristics for a wind-wheel

Generalized counter-rotating oscillators: Mixed synchronization [PDF]
Communications in Nonlinear Science and Numerical Simulation, 2015 In this paper, we report mixed synchronization between two counter rotating chaotic oscillators. We describe a procedure how to obtain a counter rotating oscillator for generalized oscillators. We elaborate the method with numerical examples of the Sprott system, Pikovsky-Rabinovich (PR) circuit model.

A NOTE ON THE CYLINDRICAL COLLAPSE OF COUNTER-ROTATING DUST [PDF]
International Journal of Modern Physics D, 2002 We find analytical solutions describing the collapse of an infinitely long cylindrical shell of counter-rotating dust. We show that — for the classes of solutions discussed herein — from regular initial data a curvature singularity inevitably develops, and no apparent horizons form, thus in accord with the spirit of the hoop conjecture.

Tracing the External Origin of the AGN Gas Fueling Reservoir
Frontiers in Astronomy and Space Sciences, 2018 Near-infrared observations of the active galaxy MCG–6-30-15 provide strong evidence that its molecular gas fueling reservoir is of external origin. MCG–6-30-15 has a counter-rotating core of stars within its central 400 pc and a counter-rotating disc of ...

Wind tunnel tests of stratospheric airship counter rotating propellers
Theoretical and Applied Mechanics Letters, 2015 Aerodynamic performance of the high-altitude propeller, especially the counter rotation effects, is experimentally studied. Influences of different configurations on a stratospheric airship, included 2-blade counter-rotating propeller (CRP), dual 2-blade

Unstable simultaneous whirl of two cylinders in a concentric double rotating cylinder system
Mechanical Engineering JournalThis study investigated the unstable simultaneous whirl of two cylinders in a concentric double rotating cylinder system, with both co- and counter-rotation. The axes of both cylinders were radially elastically supported independently of each other.
