A Modified Alpha Function for Peng-Robinson Cubic Equation of State

open access: yesChemical Engineering Transactions, 2020
A piecewise alpha function was proposed for the Peng-Robinson equation of state (PR EoS) to predict the thermodynamic properties of pure compounds. The proposed alpha function and its derivations satisfied the requirement of consistency test.

A high-efficient and salt-rejecting 2D film for photothermal evaporation

open access: yesiScience, 2023
Summary: The solar-driven desalination is seen as a sustainable way to combat water scarcity. However, the solar steam generation efficiency has long been restricted by the high vaporization enthalpy of water and low energy density of natural sunlight ...

A numerical model for the fractional condensation of pyrolysis vapours [PDF]

open access: yes, 2015
Experimentation on the fast pyrolysis process has been primarily focused on the pyrolysis reactor itself, with less emphasis given to the liquid collection system (LCS). More importantly, the physics behind the vapour condensation process in LCSs has not

Calculation of Five Thermodynamic Molecular Descriptors by Means of a General Computer Algorithm Based on the Group-Additivity Method: Standard Enthalpies of Vaporization, Sublimation and Solvation, and Entropy of Fusion of Ordinary Organic Molecules and Total Phase-Change Entropy of Liquid Crystals

open access: yesMolecules, 2017
The calculation of the standard enthalpies of vaporization, sublimation and solvation of organic molecules is presented using a common computer algorithm on the basis of a group-additivity method.

Thermodiffusion in binary liquids: the role of irreversibility [PDF]

open access: yes, 2013
We study thermal diffusion in binary mixtures in the framework of non-equilibrium thermodynamics. Our formal result displays the role of partial enthalpies and Onsager's generalized mobilities.
