Prediction of Leidenfrost Temperature in Spray Cooling for Continuous Casting and Heat Treatment Processes

open access: yesMetals, 2020
Spray cooling of hot steel surfaces is an inherent part of continuous casting and heat treatment. When we consider the temperature interval between room temperature and for instance 1000 °C, different boiling regimes can be observed.

How to Construct a Combined S-CO2 Cycle for Coal Fired Power Plant?

open access: yesEntropy, 2018
It is difficult to recover the residual heat from flue gas when supercritical carbon dioxide (S-CO2) cycle is used for a coal fired power plant, due to the higher CO2 temperature in tail flue and the limited air temperature in air preheater. The combined

Heat Flow on Alexandrov Spaces [PDF]

open access: yesCommunications on Pure and Applied Mathematics, 2012
AbstractWe prove that on compact Alexandrov spaces with curvature bounded below the gradient flow of the Dirichlet energy in the \documentclass{article} \usepackage{mathrsfs} \usepackage{amsmath, amssymb} \pagestyle{empty} \begin{document} \begin{align*}L^2\end{align*} \end{document}‐space produces the same evolution as the gradient flow of the ...

Mantle heat flow [PDF]

open access: yesEarth and Planetary Science Letters, 1977
A map of the heat flux out of the earth's mantle has been prepared by subtracting the heat flow arising in the earth's crust from the surface heat flow. In continental areas the crustal contribution of the enriched zone is determined from the parameters of the linear heat flow-heat production relationship q o = q* + bA 0 in areas where such data exist.
