Emergence of Coupled Rotor Dynamics in Metal-Organic Frameworks via Tuned Steric Interactions. [PDF]
J Am Chem Soc, 2021 The organic components in metal–organic frameworks (MOFs) are unique: they are embedded in a crystalline lattice, yet, as they are separated from each other by tunable free space, a large variety of dynamic behavior can emerge.

Atrial Rotor Dynamics Under Complex Fractional Order Diffusion. [PDF]
Front Physiol, 2018 The mechanisms of atrial fibrillation (AF) are a challenging research topic. The rotor hypothesis states that the AF is sustained by a reentrant wave that propagates around an unexcited core.

The Influence of Rotor Unbalance on Turbocharger Rotor Dynamics
Journal of Middle European Construction and Design of Cars, 2015 This paper describes the influence of an unbalance on turbocharger rotor dynamics. The structural model of the turbocharger rotor and the hydrodynamic model of the journal floating ring bearing are described and assembled in multibody dynamics software ...

Nonlinear dynamics of a Jeffcott rotor with torsional deformations and rotor-stator contact
International Journal of Non-Linear Mechanics, 2017 The dynamics of a modified Jeffcott rotor is studied, including rotor torsional deformation and rotor-stator contact. Conditions are studied under which the rotor undergoes either forward synchronous whirling or self-excited backward whirling motions ...

Dynamics and efficiency of Brownian rotors [PDF]
The Journal of Chemical Physics, 2008 Brownian rotors play an important role in biological systems and in future nanotechnological applications. However the mechanisms determining their dynamics, efficiency, and performance remain to be characterized. Here the F0 portion of the F-ATP synthase is considered as a paradigm of the Brownian rotor.

Quincke rotor dynamics in confinement: rolling and hovering. [PDF]
Soft Matter, 2019 The Quincke effect is an electrohydrodynamic instability which gives rise to a torque on a dielectric particle in a uniform DC electric field. Previous studies reported that a sphere initially resting on the electrode rolls with steady velocity.

Investigation on the Rotordynamic Characteristics of Turbopumps with Angular Contact Ball Bearings
Vibration, 2023 The support stiffness of the turbopump rotor system with angular contact ball bearing varies with the rotational speed, which leads to the inaccurate prediction of the dynamics of the turbopump rotor system.
