چکیده

We calculate the evaporative cooling dynamics of trapped one-dimensional Bose-Einstein condensates for parameters leading to a range of condensates and quasicondensates in the final equilibrium state, using the classical fields method. We confirm that solitons are created during the evaporation process by the Kibble-Zurek mechanism, but subsequently dissipate during thermalization. However, their signature remains in the phase coherence length, which is approximately conserved during dissipation in this system.

Exergy Analysis of Evaporative Cooling for Optimum Energy Consumption in Diverse Climate Conditions

In this paper, exergy of conditioned air, exergy efficiency, irreversibility, and entropy generation of common models of evaporative cooling have been investigated in five cities of Iran. Direct evaporative cooling (DEC), indirect evaporative cooling (IEC), and two-stage IEC/DEC as the most popular methods of cooling have been modeled. Atmospheric conditions are considered as the dead state of ...

Design and construction of evaporative local cooling coatings and evaluate their efficiency in improving some perceptual indicators in laboratory conditions

Introduction: One way to reduce the level of heat strain is to use personal evaporative cooling coats. such as the wrist, ankle, head and neck. The purpose of this study is to design, construct, and determine the cooling power of local cooling coatings and evaluate their efficiency in improving perceptual indicators in the laboratory. Materials and Methods: Initially, the design and constructio...

Effect of Using Evaporative Condenser Instead of Air Condenser in Window-air Conditioners

In this paper,&#10 the application of evaporative cooling for refrigeration cycle to reduce power consumption in hot climates is emphasized. Experimental and analytical investigations were performed in order to specify the effect of evaporative cooling condenser instead of the commonly used air cooling condenser in window-air-conditioners. Evaporative condenser can reject more heat, thereby pre...

Growth of a Bose-Einstein condensate: A detailed comparison of theory and experiment

We extend the earlier model of condensate growth of Davis et al [Davis MJ, Gardiner CW and Ballagh RJ 2000 Phys. Rev. A 62 063608] to include the effect of gravity in a magnetic trap. We carry out calculations to model the experiment reported by Köhl et al [Köhl M, Davis MJ, Gardiner CW, Hänsch T and Esslinger T, Preprint cond-mat/0106642] who study the formation of a rubidium Bose-Einstein con...
