The Condenser Problem

open access: yesThe Annals of Probability, 1977
The condenser theorem in classical potential theory is studied within the framework of Markov processes and probabilistic potential theory. The condenser charge is expressed in terms of successive balayages of a capacitary measure.

Enhancement of Condensation Heat Transfer Rate of the Air-Steam Mixture on a Passive Condenser System Using Annular Fins

open access: yesEnergies, 2017
This paper presents an experimental investigation on the enhancement of the heat transfer rate of steam condensation on the external surfaces of a vertical tube with annular fins. A cylindrical condenser tube, which is 40 mm in outer diameter and 1000 mm

Investigating the Dehumidification Characteristics of Turbine Stator Cascades with Parallel Channels

open access: yesEnergies, 2018
Steam turbines play a vital role in the power industry. The efficiency of the steam turbine can be improved by reforming the flow structure. For the White cascade, a parallel channel which is an additional steam passage was designed to connect adjacent ...

Formation of PAHs and Carbonaceous Solids in Gas-Phase Condensation Experiments [PDF]

open access: yes, 2009
Carbonaceous grains represent a major component of cosmic dust. In order to understand their formation pathways, they have been prepared in the laboratory by gas-phase condensation reactions such as laser pyrolysis and laser ablation.

Synthesis and Properties of Condensed Lumazine-Ringsystems

open access: yesPteridines, 2002
1,3-Dimethyllumazine-6,7-diamine (1) and its monomethyl -(3,4) and monophenylamino (5) derivates are interesting starting materials for the synthesis of imidazo[4,5-g] (6-22) and pyrazino[2,3-g]lumazines (23-26).

CFD Simulation of Defogging Effectivity in Automotive Headlamp

open access: yesEnergies, 2019
In the past decade, the condensation of internal air humidity in automotive headlamps has become more prevalent than ever due to the increased usage of a new light source—LEDs. LEDs emit far less heat than previously-used halogen lamps, which makes

Meson Condensation [PDF]

open access: yesParticles, 2019
We give a pedagogical review of the properties of the various meson condensation phases triggered by a large isospin or strangeness imbalance. We argue that these phases are extremely interesting and powerful playground for exploring the properties of hadronic matter. The reason is that they are realized in a regime in which various theoretical methods

A time-domain finite element model reduction method for viscoelastic linear and nonlinear systems

open access: yesLatin American Journal of Solids and Structures
Many authors have shown that the effective design of viscoelastic systems can be conveniently carried out by using modern mathematical models to represent the frequency- and temperature-dependent behavior of viscoelastic materials.

Expeditious, mechanochemical synthesis of BODIPY dyes

open access: yesBeilstein Journal of Organic Chemistry, 2013
BODIPY dyes have been synthesized under solvent-free or essentially solvent-free conditions, within about 5 minutes in an open-to-air setup by using a pestle and mortar, with yields that are comparable to those obtained via traditional routes that ...
