Evaporative cooling in a radio-frequency trap [PDF]

, 2006
A theoretical investigation for implementing a scheme of forced evaporative cooling in radio-frequency (rf) adiabatic potentials is presented. Supposing the atoms to be trapped by a rf field RF1, the cooling procedure is facilitated using a second rf ...

Theory of evaporative cooling with energy-dependent elastic scattering cross section and application to metastable helium

, 2003
The kinetic theory of evaporative cooling developed by Luiten et al. [Phys. Rev. A 53, 381 (1996)] is extended to include the dependence of the elastic scattering cross section on collision energy.

Comparison on cooling performance of pre-cooled natural draft dry cooling towers using nozzles spray and wet medium

Case Studies in Thermal Engineering, 2021
Evaporative pre-cooling technology improves the cooling performance of natural draft dry cooling towers (NDDCTs) by introducing a certain amount of water into the air entrance. This paper compares the effects of different evaporative pre-cooling systems (

Computational Fluid Dynamics Analysis of an Evaporative Cooling System

Journal of Mechanical Engineering, 2016
The use of chlorofluorocarbon based refrigerants in the air-conditioning system increases the global warming and causes the climate change. The climate change is expected to present a number of challenges for the built environment and an evaporative ...

Evaporative cooling of trapped fermionic atoms

, 1999
We propose an efficient mechanism for the evaporative cooling of trapped fermions directly into quantum degeneracy. Our idea is based on an electric field induced elastic interaction between trapped atoms in spin symmetric states.
