Study On Acoustic Characteristics Of Internal Leakage Of Micro-start Spring Safety Valve

open access: yesJournal of Applied Science and Engineering, 2023
To investigate the noise radiation in the leakage of the safety valve. The acoustic fluid-solid coupling simulation analysis of the leakage process of the safety valve is used to study the flow field when the safety valve is leaking.

Femtosecond Pump-Probe Diagnostics Of Preformed Plasma Channels [PDF]

open access: yes, 2004
We report on recent ultrafast pump-probe experiments 28 in He plasma waveguides using 800 nm, 80 fs pump pulses of 0.2 x 1018 W/cm2 peak guided intensity, and single orthogonally-polarized 800 nm probe pulses with similar to0.1% of pump intensity.

Study on the Cavitation Performances and Unsteady Characteristics of a Centrifugal Fire Pump [PDF]

open access: yesJournal of Applied Fluid Mechanics
Centrifugal fire pumps are critical for firefighting systems but suffer from cavitation and instability under off-design conditions. However, systematic analyses of their flow-rate-dependent dynamics remain limited. This study systematically investigates

Research on Fault Diagnosis Method of Electro-Hydrostatic Actuator

open access: yesShock and Vibration, 2021
Electrohydrostatic actuator is a type of actuator that uses hydraulic energy as the energy transmission carrier, which has the advantages of small size and high power. Since it is commonly used in harsh conditions such as strong vibration, high pressure,

Theory of cw Raman oscillation in optical fibers [PDF]

open access: yes, 1979
A theory for Raman fiber laser oscillators is presented. The Stokes output and the residual pump power are shown to be calculable from a knowledge of the input pump power and the fiber characteristics. The evolution of the pump and the Stokes waves along

Resonant pumping in a multilayer impedance pump [PDF]

open access: yes, 2008
This paper introduces the concept of multilayer impedance pump, a novel pumping mechanism inspired by the embryonic heart structure. The pump is a composite two-layer fluid-filled elastic tube featuring a thick gelatinous internal.
