Availability Analysis For Heterogeneous Nucleation In A Uniform Electric Field
Authors
Abstract:
Industrial demands for more compact heat exchangers are a motivation to find new technology features. Electrohydrodynamics (EHD) is introduced as a promising phenomenon for heat transfer enhancement mechanisms. Similar to any new technology, EHD has not been understood completely yet and requires more fundamental studies. In boiling phase change phenomena, nucleation is the dominant mechanism in heat transfer. Because of higher performance in heat transfer, nucleate boiling is considered as the main regime in thermal components. Hence, bubble dynamic investigation is a means to evaluate heat transfer. This study investigates bubble formation, including homogeneous and heterogeneous nucleation, from a thermodynamic point of view. Change in availability due to bubble embryo nucleation is discussed. Stability criteria for these systems are theoretically studied and results are discussed considering experimental data. In addition, a conceptual discussion on entropy generation in a thermodynamic system under electric field is presented.

Born-Infeld Dynamics in Uniform Electric Field
We investigate various properties of classical configurations of the Born-Infeld theory in a uniform electric field. This system is involved with dynamics of (F,Dp) bound states, which are bound states of fundamental strings and Dp-branes. The uniform electric field can be treated as a constraint on the asymptotic behavior of the fields on the brane. BPS configurations in this theory correspond...

full textNeutral donor-acceptor-pair recombination under a uniform electric field.
The kinetics of the recombination of electrons trapped by donors, with holes trapped by acceptors, in semiconductor materials within a uniform electric field has been investigated. A simple form has been derived which shows that the decay rate of neutral donor-acceptor-pair {DAP) recombination increases under the presence of the electric field. This analysis can also be applied to the processes...
full textStatic safety analysis for non-uniform service availability in Actors
Introduction The main purpose of this work is the static detection of orphan messages in actor based languages. An orphan is a message which may not be handled by its target in some execution paths. Two kinds of orphan messages may be encountered : safety ones and liveness ones. Safety orphans occur when all target behaviors on a given execution path do not know how to handle the message. Liven...
