The baryon fraction in hydrodynamical simulations of galaxy clusters

, 2005
We study the baryon mass fraction in a set of hydrodynamical simulations of galaxy clusters performed using the Tree+SPH code GADGET-2. We investigate the dependence of the baryon fraction upon the radiative cooling, star formation, feedback through ...

SPH and Radiative Cooling [PDF]

International Astronomical Union Colloquium, 2004
I have investigated the effects of including a more realistic cooling law in SPH simulations of accretion discs. In order to improve the efficiency of the simulations, I have used Strang operator splitting, and I have developed a method of timestep control which guarantees the accuracy and stability of the simulations.Strang splitting (Strang, 1968) is

Radiative Cooling for Energy Sustainability: From Fundamentals to Fabrication Methods Toward Commercialization

Advanced Science
Radiative cooling, a technology that lowers the temperature of terrestrial objects by dissipating heat into outer space, presents a promising ecologically‐benign solution for sustainable cooling.

Metal Cooling in Simulations of Cosmic Structure Formation

, 2007
The addition of metals to any gas can significantly alter its evolution by increasing the rate of radiative cooling. In star-forming environments, enhanced cooling can potentially lead to fragmentation and the formation of low-mass stars, where metal ...

Hydrodynamic Simulations of Galaxy Formation. I. Dissipation and the Maximum Mass of Galaxies

, 1994
We describe an accurate, one-dimensional, spherically symmetric, Lagrangian hydrodynamics/gravity code, designed to study the effects of radiative cooling and photo-ionization on the formation of protogalaxies.

Modeling radiation in particle clouds: On the importance of inter-particle radiation for pulverized solid fuel combustion

, 2014
The importance of inter-particle radiation for clusters of gray and diffuse particles is investigated. The radiative cooling of each individual particle is found to vary strongly with its position in the cluster, and a mean radiative particle cooling ...

Development of a PCM-Integrated Radiant Cold-Storage System: Radiative-Cooling Film, Water Tank Design, and Outdoor Performance Validation

Energies
Outdoor environments typically require intensive cooling during the day, while nighttime cooling demands are comparatively modest. Conventional radiative-cooling systems deliver strong cooling at night but often underperform during daytime solar exposure.

Daytime Radiative Cooling under Extreme Weather Conditions

Advanced Energy & Sustainability Research
Radiative cooling, taking advantage of the coldness of the sky, has a potential to be a sustainable alternative to meet cooling needs. The performance of a radiative cooling device is fundamentally limited by the emissivity of the sky, therefore depends ...

Vertical Structure of Gas Pressure-Dominated Accretion Disks with Local Dissipation of Turbulence and Radiative Transport

, 2005
(shortened) We calculate the vertical structure of a local patch of an accretion disk in which heating by dissipation of MRI-driven MHD turbulence is balanced by radiative cooling.
