Nonlinear Coupled Motions of a Pipe-in-Pipe System Experiencing Vortex-Induced Vibrations
Nonlinear Dynamics, 2023 Abstract This paper delves into the dynamics of the pipe-in-pipe system, crucial in offshore oil and gas exploration, featuring an inner drill string nestled within an outer riser. A reduced-order model with five degrees of freedom is proposed to capture the coupled dynamics of this system.

Flux Pipe Pads with Improved Coupling Characteristics
2019 16th International Multi-Conference on Systems, Signals & Devices (SSD), 2019 In this paper, flux pipe pad structure is discussed focusing on the analyzing effects of the number of sub-coils and separation between sub-coils on the coupling performance. Simulations show that the flux pipe pads with three or more sub-coils exhibit higher magnetic coupling coefficient as compared to traditional flux-pipe pads with two sub-coils. In

Vibration of a flexible pipe conveying viscous pulsating fluid flow [PDF]
, 2000 The non-linear equations of motion of a flexible pipe conveying unsteadily flowing fluid are derived from the continuity and momentum equations of unsteady flow. These partial di!erential equations are fully coupled through equilibrium of contact forces,

“Pipe organ” air-coupled broad bandwidth transducer [PDF]
2017 IEEE International Ultrasonics Symposium (IUS), 2017 Air-coupled transducers are used to conduct fast non-contact inspections in NDT. Normally, the bandwidth of a conventional transducer can be enhanced, but with a cost to its sensitivity. However, low sensitivity is very disadvantageous in air-coupled devices. This paper presents a methodology for improving the bandwidth of an air-coupled micro-machined
