Synchronization in counter-rotating oscillators [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2011 An oscillatory system can have opposite senses of rotation, clockwise or anticlockwise. We present a general mathematical description of how to obtain counter-rotating oscillators from the definition of a dynamical system. A type of mixed synchronization emerges in counter-rotating oscillators under diffusive scalar coupling when complete ...

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.

Noise Source Analysis in Counter-Rotating Open Rotors [PDF]
AIAA Journal, 2022 Because of their potential to reduce aircraft emissions, counter-rotating open rotors (CRORs) have seen a renewed interest in applications, from civil aviation to urban air mobility. However, there are concerns surrounding their acoustic emissions. In the work presented, the authors investigated the noise sources for a range of CROR configurations for ...

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.

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

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 ...

Kelvin–Helmholtz instability of counter-rotating discs [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 Observations of galaxies and models of accreting systems point to the occurrence of counter-rotating discs where the inner part of the disc ...

Counter-rotating black holes from FRII lifetimes
Frontiers in Astronomy and Space Sciences, 2023 Estimates suggest that while FRII jets appear to have lifetimes constrained to hundreds of millions of years, radio galaxies with FRI jets appear to be longer lived.

Emerging chimera states under nonidentical counter-rotating oscillators
Physical Review E, 2022 Frequency plays a crucial role in exhibiting various collective dynamics in the coexisting co- and counter-rotating (CR) systems. To illustrate the impact of CR frequencies, we consider a network of non-identical and globally coupled Stuart-Landau oscillators with additional perturbation.
