Nonequilibrium model of water generation in Aircraft Fuel Tanks
To investigate the formation of water contaminants in fuel tanks, a nonequilibrium model based on heat and mass transfer is established, and the dissolved water, suspended water, condensed water, free water are analyzed under different conditions.

Submanifolds with curvature normals of constant length and the Gauss map [PDF]
We show that a submanifold with curvature normal of constant length has constant principal curvatures under suitable global hypothesis.

Photon noise and constant-volume operators [PDF]
In an earlier paper [J. Opt. Soc. Am. A 2, 1769 (1985)] a class of nonlinear image processing operators was introduced in which each photoreceptor creates a nonnegative point-spread function whose center height is proportional to its quantum catch and whose volume is constant, so that the local spatial-summation area varies inversely with the local ...

Carbonization of Biomass in Constant-Volume Reactors
A novel carbonization process that realizes near-theoretical fixed-carbon yields in ~3 h is presented. Norwegian spruce and birch sawdusts were carbonized in a hermetically-sealed reactor at an initial nitrogen pressure of 0.1 MPa. During a carbonization test, the reactor vessel retained all pyrolytic products inside the hot reaction zone invoking high

Constant volume combustion of aluminum and cornstarch dust in microgravity
The subject of the present work is to report an experimental comparative study of the effect of dispersion-induced turbulence on dust combustion in constant volume vessel, carried out both in normal gravity and in microgravity environment.

On the Volume of Sets Having Constant Width† [PDF]
Let C be a set of constant width d in \({\mathbb{R}}^ n\). Besides other interesting results, a lower bound for the volume of C is given. Namely, if Vol B(d/2) denotes the n-dimensional volume of a ball B in \({\mathbb{R}}^ n\) with radius d/2, then \[ Vol C\geq (\sqrt{3+2/(n+1)}-1)^ n\cdot Vol B(d/2) \] holds.

Experimental Study of Constant Volume Sulfur Dust Explosions
Dust flames have been studied for decades because of their importance in industrial safety and accident prevention. Recently, dust flames have become a promising candidate to counter biological warfare. Sulfur in particular is one of the elements that is

Experimental studies on constant mass–volume depletion of gas-condensate systems
This paper presents a new empirical model to estimate dew point pressure Pd for gas condensate reservoirs as a function of routinely measured gas analysis and reservoir temperature.

Quasi-constant volume (QCV) spark ignition combustion [PDF]
The Otto cycle delivers theoretical maximum thermal efficiency. The traditional design of internal combustion engines using a simple slide-crank mechanism gives no time for a constant volume combustion which significantly reduces the cycle efficiency. In
