Bernoulli’s equation, energy and enthalpy [PDF]

open access: yesRevista Brasileira de Ensino de Física
In this paper, we expose and compare two different physical interpretations of Bernoulli’s equation. One interpretation is that pressure must be a type of potential energy density, and Bernoulli’s equation means the uniformity of the mechanical energy ...

Comparison and verification of enthalpy schemes for polythermal glaciers and ice sheets with a one-dimensional model [PDF]

open access: yes, 2015
The enthalpy method for the thermodynamics of polythermal glaciers and ice sheets is tested and verified by a one-dimensional problem (parallel-sided slab).

Comparison of modified alpha functions of the PR-EoS for volume and enthalpy prediction of natural gases [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2020
Proper simulation of processes of the natural gas industry such as dehydration, liquefaction and regasification require accurate prediction of thermodynamic properties of the working fluids.

Bayesian Statistical Mechanics: Entropy-Enthalpy Compensation and Universal Equation of State at the Tip of Pen

open access: yesFrontiers in Physics, 2018
This work has shown the way to put the formal statistical-mechanical basement under the hotly debated notion of enthalpy-entropy compensation. The possibility of writing down the universal equation of state based upon the statistical mechanics is ...

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.

Change of Compressiblity at the Glass Transition and Prigogine-Defay Ratio in ZrTiCuNiBe Alloys [PDF]

open access: yes, 1999
The change of the compressibility at the glass transition Tg is evaluated from pressure experiments in the liquid and the glassy state of the ZrTiCuNiBe bulk metallic glass forming system.

Modeling of Heat Stress in Sows Part 2: Comparison of Various Thermal Comfort Indices

open access: yesAnimals, 2021
Heat stress has an adverse effect on the production performance of sows, and causes a large economic loss every year. The thermal environment index is an important indicator for evaluating the level of heat stress in animals.

Formulations of moist thermodynamics for atmospheric modelling

open access: yes, 2015
Internal energy, enthalpy and entropy are the key quantities to study thermodynamic properties of the moist atmosphere, because they correspond to the First (internal energy and enthalpy) and Second (entropy) Laws of thermodynamics.
