Pressure fluctuations on gates
Journal of Hydraulic Research, 1989Mean and fluctuating pressures on various geometries of vertical-lift gates have been measured and analysed. The influence of various hydraulic parameters and the magnitude of the gate opening on mean and r.m.s. pressure fluctuations and their spatial correlations has been investigated.

Physica, 1973
Abstract The old problem of pressure fluctuations is analyzed in terms of three characteristic times: (1) the duration of a molecular collision with the wall, (2) the time between successive collisions by a specific molecule, and (3) the integrating time of the pressure-measuring instrument.

The intense vibration accompanying the extension of dive brakes and other high-drag devices on aircraft and missiles has been observed for many years. Recently, considerable vibration has been experienced at the fundamental longitudinal mode and at other internal resonance frequencies of a vehicle which had a blunt base during the maximum dynamic ...

Energy Harvesting From Hydraulic Pressure Fluctuations
Volume 2: Mechanics and Behavior of Active Materials; Integrated System Design and Implementation; Bio-Inspired Materials and Systems; Energy Harvesting, 2012State-of-the-art hydraulic hose and piping systems employ integral sensor nodes for structural health monitoring in order to avoid catastrophic failures. These systems lend themselves to energy harvesting for powering sensor nodes. The foremost reason is that the power intensity of hydraulic systems is orders of magnitude higher than typical energy ...

Pressure drop fluctuations in periodically fluctuating pipe flow
Journal of Marine Science and Application, 2010Experiments were conducted to study characteristics of flow when flow is fluctuating. The experimental results showed a phase difference between the flow rate and the pressure drop fluctuations. This phase difference between the fluctuating flow rate and pressure drop was analyzed for laminar flow. Analysis showed that the phase difference changes with

The discrimination of blood pressure fluctuations
Biological Psychology, 1979Two studies are described in which volunteers were trained to distinguish between displays contingent on or independent of blood pressure fluctuations. The latter were monitored with pulse transit time (TT). In Experiment 1, subjects were required to choose between TV displays that either reflected instantaneous TT or variations recorded a few minutes ...

Fluctuating Pressures on Mildly Indented Nosetips
Journal of Spacecraft and Rockets, 1978Fluctuating pressure measurements at M = 5.0 are presented for turned (axisymmetric) nose shapes that represent approximations of cross sections (at various meridians) of the recovered graphite nosetip of the Nosetip Recovery Vehicle (NRV). Selected fluctuating pressure measurements are also presented for a replica of the NRV nosetip and a replica of a
