Spinning detonation and velocity deficit in small diameter tubes

Proceedings of the Combustion Institute, 2009
Abstract Detonation velocities and soot patterns of H2/O2 mixtures were measured in glass tubes of 3, 6 and 10 mm diameters at pressures ranging from 70 to 400 Torr and equivalence ratios of 0.5–1.5. It was confirmed that the transition from a multi-head to a spinning detonation occurred at the pressure where the cell size is equal to the length of ...

Deficit and change in gait velocity during rehabilitation after stroke.

Archives of Physical Medicine and Rehabilitation, 1996
To quantify the initial deficit, change, and outcome in gait velocity during inpatient rehabilitation following stroke.The initial deficit on admission to rehabilitation was quantified by comparing 42 stroke patients with 42 controls matched by gender and age. The change in the stroke patients during the next 8 weeks was quantified and gait outcome was

Detonation velocity deficit and curvature radius of flexible detonation fuses

Combustion, Explosion, and Shock Waves, 2012
The detonation velocity deficit in bending flexible detonating fuses is studied, based on the detonation wave’s corner effects and delay time phenomenon. A physical model and a theoretical mathematical equation of the detonation velocity deficit are established by using the dimensional analysis.

Effect of turbulence on the downstream velocity deficit of a rigid sphere

Physics of Fluids, 2011
The effect of external turbulence completely modifies how the velocity deficit behind a rigid sphere decays with distance, changing it from an x−1 (or x−2/3 depending on the Reynolds number characterising the flow past the sphere) to x−2 decay, where x is the distance downstream. The wake width is observed to grow linearly with x.

Effects of Movement Velocity and Maximal Concentric and Eccentric Actions on the Bilateral Deficit

Research Quarterly for Exercise and Sport, 2006
Department of Health, Physical Education, Recreation, and Dance at the University of Idaho. This study was performed to examine the effects of movement velocity and maximal concentric and eccentric actions on the bilateral deficit. Eighteen female participants performed maximal unilateral and bilateral knee extensions concentrically and eccentrically ...

The effect of boundaries on the velocity deficit and the limit of gaseous detonations

Combustion Science and Technology, 1971
Abstract Effects of boundaries on the gaseous detonation velocity and on detonability limits are examined. A generalized Karman-Pohlhausen procedure is employed to obtain a system of quasi one-dimensional equations which include the boundary effects correctly.

Detonation velocity deficits of H2/O2/Ar mixture in round tube and annular channels

International Journal of Hydrogen Energy, 2015
Abstract In this study, a series of experiments have been carried out to determine the detonation velocity deficits of 2H2–O2 and 2H2–O2–3Ar mixtures in narrow gaps. Those gaps include a 36 mm inner round tube and three annular channels gaps (w = 2 mm, 4.5 mm and 7 mm, w is the gap of annular channel).

Bilateral deficit magnitude increases with velocity during a half-squat exercise

Journal of Sports Sciences, 2022
Movement velocity has been viewed as one of the bilateral deficit (BLD) determinants. This research tested the velocity effect on BLD during a half-squat exercise. The role of muscle excitation in BLD was also assessed. BLD amplitude was assessed in 12 male soccer players while performing a half-squat exercise with incremental load. During the exercise'

New Constraints on Slip Deficit on the Aleutian Megathrust and Inflation at Mt. Veniaminof, Alaska From Repeat GPS Measurements

Geophysical Research Letters, 2021
We employ an enhanced data set of Global Positioning System (GPS) velocities to reassess the slip deficit along the plate interface of the Alaska‐Aleutian subduction zone. An examination of velocities of sites near Mt Veniaminof, located in the southwest
