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,

Fluids, 2021 The presence of spherical solid particles immersed in an incompressible turbulent flow was numerically investigated from the perspective of the particle mass fraction (PMF or ϕm), a measure of the particle-to-fluid mass ratio.

“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

Evaluation of the effects of a load shedding at a lignite power plant
Energy Science & Engineering, 2021 The load‐shedding scenario describes an unscheduled load reduction in a power plant so that it produces only the electricity that is needed by the plant itself. The reason for such a scenario is a collapse of power supply in the transmission network.

Hurricane Sandy and engineered response created habitat for a threatened shorebird
Ecosphere, 2019 The intensity of Atlantic Ocean hurricanes is predicted to increase, and although disturbance is recognized as a fundamental driver of ecological processes, the benefits of hurricanes to ecological systems are seldom acknowledged.

Plastic collapse of pipe bends under combined internal pressure and in-plane bending [PDF]
, 2005 Plastic collapse of pipe bends with attached straight pipes under combined internal pressure and in-plane closing moment is investigated by elastic–plastic finite element analysis.

Experimental Investigation on the Acoustic Scattering Matrix for a Centrifugal Pump
Proceedings, 2018 Fluid-dynamic noise in centrifugal pumps as a significant sound source in piping systems has gained high attention due to the requirements of vibration and noise reduction in many fields. The acoustic characteristics of the fluid-dynamic noise from pumps

Review on the current state of developing of advanced Creep Damage Constitutive Equations for high Chromium Alloy [PDF]
, 2012 This paper presents a review of developing of creep damage constitutive equations for high chromium alloy (such as P91 alloy). Firstly, it briefly introduces the background of creep damage for P91 materials.
