Exergy Efficiency for Radiation Heat Transfer

IOP Conference Series: Materials Science and Engineering, 2020
Abstract One of the evaluation criteria for the performance of thermal processes is exergy analysis. Along with energy analysis, exergy calculations provide a clear and highly effective understanding of the performance of a system. Although exergy analysis has been extensively applied to many industrial processes, there are limited works

Heating efficiency in hydrogen-dominated upper atmospheres

, 2014
Context. The heating efficiency is defined as the ratio of the net local gas-heating rate to the rate of stellar radiative energy absorption. It plays an important role in thermal-escape processes from the upper atmospheres of planets that are exposed to

Efficient Heat-Bath Sampling in Fock Space [PDF]

Journal of Chemical Theory and Computation, 2016
We introduce an algorithm for sampling many-body quantum states in Fock space. The algorithm efficiently samples states with probability approximately proportional to an arbitrary function of the second-quantized Hamiltonian matrix element connecting the sampled state to the current state.

Shape of the inflaton potential and the efficiency of the universe heating [PDF]

, 2015
It is shown that the efficiency of the universe heating by an inflaton field depends not only on the possible presence of parametric resonance in the production of scalar particles but also strongly depends on the character of the inflaton approach to ...
