Condensation: Passenger Not Driver in Atmospheric Thermodynamics

open access: yesEntropy, 2016
The second law of thermodynamics states that processes yielding work or at least capable of yielding work are thermodynamically spontaneous, and that those costing work are thermodynamically nonspontaneous.

The Evaporation Valley in the Kepler Planets [PDF]

open access: yes, 2017
A new piece of evidence supporting the photoevaporation-driven evolution model for low-mass, close-in exoplanets was recently presented by the California–Kepler Survey. The radius distribution of the Kepler planets is shown to be bimodal, with a “valley”

Quantum Cooling Evaporation Process in Regular Black Holes [PDF]

open access: yes, 2007
We investigate a universal behavior of thermodynamics and evaporation process for the regular black holes. We newly observe an important point where the temperature is maximum, the heat capacity is changed from negative infinity to positive infinity, and

Pressure-Driven Evaporative Cooling in Atom Guides

open access: yes, 2014
We study steady-state evaporation in an atom guide via Monte Carlo simulations. The evaporation surface follows a specific profile as a function of longitudinal guide location.

Prediction of thermal transport characteristics of microgroove evaporator (Validation of prediction model by measurement of transported heat and capillary-rise length)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
A microgroove evaporator is expected to achieve a high heat transfer coefficient despite its simple structure. However, the mechanism of high heat flux in association with the groove structure is still not clear enough to design its thermal performance ...
