Detonation propagation with velocity deficits in narrow channels

Proceedings of the Combustion Institute, 2011
Abstract Propagation limits of detonations in narrow channels have been studied with a focus on velocity deficits and variation in cell widths. A channel was formed by a pair of metal plates of 1500 mm length which were inserted in a detonation tube of 50.5 mm inner diameter.

Velocity deficits and detonability limits of hydrogen-oxygen detonations

Acta Astronautica, 1974
Abstract Velocity deficits and detonability limits of stoichiometric hydrogen-oxygen gas detonations have been calculated at subatmospheric pressures (50–760 torr), using a quasi-one-dimensional ZDN model. The effect of the viscous boundary layer was accounted for by allowing for cross-sectional area changes in the flow.

Decreased Head Circumference Velocity as Related to Developmental Deficit in Infancy

Pediatric Neurology, 2012
We evaluated the significance of head circumference growth velocity as related to developmental deficits during infancy. Head circumferences, lengths, and developmental diagnoses were retrieved in a standard manner at ≥ 2 time points from 437 infants with developmental deficits, and 3909 normally developing infants.

Detonation Velocity Deficits and Curvature Radius of Mild Detonation Cords

Propellants, Explosives, Pyrotechnics, 2011
AbstractIn order to study the detonation velocity deficits of wound mild detonation cords, a physical model and a theoretical mathematical equation for detonation velocity deficits of wound mild detonation cords were established based on the detonation wave’s corner effects and delay time phenomenon by using non‐dimensional analysis method.

A study on velocity deficits of detonation waves in narrow gaps

Proceedings of the Combustion Institute, 2002
The propagation behavior of detonation waves in narrow gaps for hydrogen/oxygen/argon mixtures has been investigated in terms of velocity deficits. The gap was formed by a pair of metal plates 500 mm in length which were inserted in a detonation tube.

Bone Ultrasound Velocity in Neonates With Intrauterine Growth Deficit Reflects a Growth Continuum

Journal of Clinical Densitometry, 2011
Both bone mass by densitometry and speed of sound (SOS) from quantitative ultrasound of the bone (QUS) are directly related to bone strength. However, reports of lower bone mass but higher SOS in neonates with intrauterine growth deficit lead to apparent contradictory conclusions on bone strength.

Force‐velocity profiling in older adults: An adequate tool for the management of functional trajectories with aging

Experimental Gerontology, 2018
Introduction: The actual mechanisms leading to a reduced muscle power and functional ability in older adults are poorly understood. We investigated the association between different force‐velocity (F‐V) profiles and impaired muscle power, physical and ...

Effects of vortex-induced velocity on the development of a synthetic jet issuing into a turbulent boundary layer

Journal of Fluid Mechanics, 2019
A synthetic jet issuing into a cross-flow influences the local velocity of the cross-flow. At the jet exit the jet is oriented in the wall-normal direction while the cross-flow is oriented in the streamwise direction, leading to a momentum transfer ...

Nerve conduction velocity measurements reveal the functional deficit in ceramide galactosyl transferase-deficient (cgt−/−) mice

Journal of the Neurological Sciences, 2004
Biochemical and ultrastructural studies of ceramide galactosyltransferase (CGT) in a CGT-deficient mouse line (cgt-/-) were complemented by nerve conduction velocity (NCV) measurements in motor nerves (sciatic nerve in the hind limbs) of wild type (wt) and cgt-/- mice.
