Detonation propagation with velocity deficits in narrow channels
Proceedings of the Combustion Institute, 2011Abstract 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.

Decreased Head Circumference Velocity as Related to Developmental Deficit in Infancy
Pediatric Neurology, 2012We 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.

Spinning detonation and velocity deficit in small diameter tubes
Proceedings of the Combustion Institute, 2009Abstract 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 ...

Effect of turbulence on the downstream velocity deficit of a rigid sphere
Physics of Fluids, 2011The 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.

Velocity deficits and detonability limits of hydrogen-oxygen detonations
Acta Astronautica, 1974Abstract 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.

A study on velocity deficits of detonation waves in narrow gaps
Proceedings of the Combustion Institute, 2002The 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.

Effects of Movement Velocity and Maximal Concentric and Eccentric Actions on the Bilateral Deficit
Research Quarterly for Exercise and Sport, 2006Department 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 ...

Force–Velocity Properties’ Contribution to Bilateral Deficit during Ballistic Push-off
Medicine & Science in Sports & Exercise, 2014The objective of this study is to quantify the contribution of the force-velocity (F-v) properties to bilateral force deficit (BLD) in ballistic lower limb push-off and to relate it to individual F-v mechanical properties of the lower limbs.The F-v relation was individually assessed from mechanical measurements for 14 subjects during maximal ballistic ...

Detonation Velocity Deficits and Curvature Radius of Mild Detonation Cords
Propellants, Explosives, Pyrotechnics, 2011AbstractIn 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.
