AbstractCharacterizing scalar dispersion is a key concern in a wide variety of applications, including both steady-state and time-dependent studies of wastewater outfalls, salinity distribution in estuaries, and the spreading of pollutants from industrial spills. As the size of a scalar plume grows with respect to the size of the containing water body,

Dynamics of the transient regime of spaser
Journal of Communications Technology and Electronics, 2011The dynamics of the nonradiative excitation of plasmons in the surface plasmon amplifier by stimulated emission of radiation (spaser) that represents a two-level quantum dot in the vicinity of the metal (plasmon) nanoparticle is considered. It is demonstrated that the steady-state generation of spaser is preceded by the regime with the oscillations at ...

The transient regime of a multiwavelength pyrometer
International Journal of Thermophysics, 1993The transient operation of a new multiwavelength pyrometer based on a dispersing prism and a Si photodiode array is presented. After calibration, transient tests were performed using a tungsten strip lamp, supplied by a current pulse of 0.3-s duration.

On the reduced moment in the transient regime of homogeneous nucleation
The Journal of Chemical Physics, 2007One of the parameters characterizing the evolution of nucleation in the transient regime is the so-called reduced moment, a dimensionless quantity. This parameter describes the steepness with which the nucleation rate approaches its steady state. Until recently, very little had been known about this parameter in real systems, although a widely quoted ...

Transient regimes in the growth of large‐diameter crystals
Crystal Research and Technology, 1988AbstractThe behaviour of crystallization rate and interface position under the change of Czochralski growth system parameters is theoretically and experimentally investigated for the case of large diameter crystals growth. It is shown that the large value of crystal diameter leads to the inertia and nonmonotonic character of system relaxation after the

Transient Ablation Regime in Circuit Breakers
Plasma Science and Technology, 2007Nozzle wall ablation caused by high temperature electric arcs is studied in the context of high voltage SF6 circuit breakers. The simplified ablation model used in litterature has been updated to take into account the unsteady state of ablation. Ablation rate and velocity are now calculated by a kinetic model using two layers of transition, between the

Generalized hydrodynamics in the transient regime and irreversible thermodynamics
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2004In this article the thermodynamically consistent formulation of generalized hydrodynamics is reviewed and applications to shock-wave structures, ultrasonic wave absorption and dispersion and microchannel flows of the generalized hydrodynamics so formulated are discussed.

Analysis of rocket-engine transient regimes
Acta Astronautica, 1977Abstract Three rocket propulsion systems are reviewed with a view to help designers in their projects, emphasizing the points they have in common and also their differences. (i) Hydrazine decomposition engines: ignition and extinction are examined, as well as thrust modulation by injection rate variations. The unstable functioning domains are defined.

Induction Motors in Transient Regimes
2001This chapter deals with the behavior of induction motors operating in the transient regime. The main purpose of transient analysis is to calculate variations in stator and rotor currents as well as variations in torque during the time interval (generally short) in which the drive leaves its old permanent regime to settle down in a new steady state ...
