in a steam power plant, the temperature of the cooling water leaving the condenser for recyclingshould decrease. this is achieved in a cooling tower. the heller cooling tower does not require waterfor operation, thus, it is a suitable system for use in thermal power plants throughout iran. wind is anenvironmental factor that unfavorably affects the performance of a cooling tower. previous studi...

Abstract Turbulent radiative mixing layers (TRMLs) form at the interface of cold, dense gas and hot, diffuse in motion with each other. TRMLs are ubiquitous around galaxies on a variety scales, including galactic winds circumgalactic medium. They host intermediate-temperature gases that efficient cooling, thus playing crucial role controlling cold supply, phase structure, spectral features gala...

Yin (NSLS, BNL) Beamline(s) X25, X13B Introduction: Silicon crystals at room temperature employed as x-ray monochromators on synchrotron radiation beamlines, when subjected to high power density loading, suffer thermal di...

[1] We explore the applicability of paired Mg/Ca and O/O measurements on benthic foraminifera from Southern Ocean site 747 to paleoceanographic reconstructions on pre-Pleistocene timescales. We focus on the late Oligocene through Pleistocene (27–0 Ma) history of paleotemperatures and the evolution of the dO values of seawater (dOsw) at a temporal resolution of 100–200 kyr. Absolute paleotempera...

a thermodynamic analysis of the counter flow wet cooling tower (cwct) in the steelmaking unit of the khuzestan steel company (ksc) is performed in this paper. we evaluated both energy and exergy formulations for analyzing the heat and mass transfer, exergy and second-law efficiency in this cooling tower. the lewis factor le f is an indication of the relative rates of heat and mass transfer in a...

heating and sudden cooling are among the most important processes affecting temper quality in the production period of tempered auto glass. in this study, heat transfer characteristics and cooling times during the sudden cooling process of tempered glass production have been experimentally investigated. flat glass with dimensions of 50x50x4 mm has been heated up to 680 ºc in the furnace and was...

The application of phase change material (PCM) for energy conservation purposes in the residential buildings was investigated in the present study. Two types of building in terms of materials as the lightweight building (LWB) and heavyweight building (HWB) located in a high cooling load demanding region of Iran were considered for the study. Different types of PCM from organic and inorganic cat...
