Green Material Prospects for Passive Evaporative Cooling Systems: Geopolymers
Passive cooling techniques have been used mostly in countries with hot and arid climates such as Iran, Egypt, and India. However, the use of this important technology has not been seriously considered until a time of energy crisis, and consequently, environmental crisis scenarios, emerge. Scholars have renewed their interest in investigating passive cooling technology, particularly the aspects ...
متن کاملEvaporative cooling of speleothem drip water
This study describes the first use of concurrent high-precision temperature and drip rate monitoring to explore what controls the temperature of speleothem forming drip water. Two contrasting sites, one with fast transient and one with slow constant dripping, in a temperate semi-arid location (Wellington, NSW, Australia), exhibit drip water temperatures which deviate significantly from the cave...
متن کاملInvestigation of Radiative Cooling Using a Photonic Composite Material for Water Harvesting
The objective of this study is to design and analyse materials which are capable of harvesting water from thin air using condensation phenomenon which employs the radiative cooling approach. These passive cooling materials not only solve the water generating problems, but also employed in various cooling applications. The fundamental concept of radiative cooling is analysed and the performance ...
متن کاملEvaporative cooling and water balance during flight in birds.
The rate of evaporative cooling was calculated from the rate of mass loss in starlings (Sturnus vulgaris) during 90 min flights in a wind-tunnel. Evaporative heat loss ranged from 5% of the metabolic rate at -5 degrees C to 19% of the metabolic rate at 29 degrees C. Radiation and convection accounted for the balance of the heat loss. On average, starlings dehydrated during flights at all temper...
متن کاملEvaporative Cooling of Continuously Drawn Glass Fibers by Water Sprays
This paper examines the effect of the water sprays commonly used to cool freshly drawn glass fibers. A model has been developed using a Karman-Pohlhausen treatment of the velocity and thermal boundary layers and accounting for the evaporation of an entrained water spray. Solutions of the model equations have been calculated, and the effect of changing various process parameters is studied. Vari...
