The Cooling of Coronal Plasmas. iv: Catastrophic Cooling of Loops [PDF]

open access: yes, 2013
We examine the radiative cooling of coronal loops and demonstrate that the recently identified catastrophic cooling (Reale and Landi, 2012) is due to the inability of a loop to sustain radiative / enthalpy cooling below a critical temperature, which can ...

Research Progress on Polymer-based Radiative Cooling Materials

open access: yesLiang you shipin ke-ji
In the process of grain storage, the use of low-temperature grain storage technology can effectively reduce grain losses during storage and ensure grain quality, which is of great significance for maintaining a stable grain supply.

Radiative cooling in polish climatic conditions

open access: yesE3S Web of Conferences, 2018
Ecological, natural ways of obtaining energy for building cooling are becoming more and more popular around the world. Reducing energy demand and increasing the renewable energy use can be achieved for example by using radiative cooling.

High‐Performance Daytime Radiative Cooler and Near‐Ideal Selective Emitter Enabled by Transparent Sapphire Substrate

open access: yesAdvanced Science, 2020
Daytime radiative cooling serving as a method to pump heat from objects on Earth to cold outer space is an attractive cooling option that does not require any energy input.

Entropy Limit and the Cold Feedback Mechanism in Cooling Flow Clusters

open access: yes, 2008
I propose an explanation to the finding that star formation and visible filaments strong in Halpha emission in cooling flow clusters occur only if the minimum specific entropy and the radiative cooling time of the intracluster medium (ICM), are below a ...

Cirrus clouds triggered by radiation, a multiscale phenomenon [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
In this study, the influence of radiative cooling and small eddies on cirrus formation is investigated. For this purpose the non-hydrostatic, anelastic model EULAG is used with a recently developed and validated ice microphysics scheme (Spichtinger and ...

Approximations for radiative cooling and heating in the solar chromosphere

open access: yes, 2012
Context. The radiative energy balance in the solar chromosphere is dominated by strong spectral lines that are formed out of LTE. It is computationally prohibitive to solve the full equations of radiative transfer and statistical equilibrium in 3D time ...

Materials in Radiative Cooling Technologies

open access: yesAdvanced Materials
AbstractRadiative cooling (RC) is a carbon‐neutral cooling technology that utilizes thermal radiation to dissipate heat from the Earth's surface to the cold outer space. Research in the field of RC has garnered increasing interest from both academia and industry due to its potential to drive sustainable economic and environmental benefits to human ...

Directional radiation for optimal radiative cooling

open access: yesOptics Express, 2021
The omnidirectional radiation scheme has been widely applied to thermal emitters for radiative cooling. We quantitatively illustrate that significant net radiative absorption at high zenith angles limits the performance of such isotropic emitters, and demonstrate that simply cutting off components corresponding to high angles can substantially improve ...

Climate model simulation of winter warming and summer cooling following the 1991 Mount Pinatubo volcanic eruption

open access: yes, 1999
We simulate climate change for the 2-year period following the eruption of Mount Pinatubo in the Philippines on June 15, 1991, with the ECHAM4 general circulation model (GCM).
