The energy equation is an expression of the first law of thermodynamics or the law of conservation of energy. First, a balance equation for the rate of change of kinetic energy and internal energy is written. Next, a separate equation for the kinetic energy is obtained by forming the dot pr...
Use of a hard sphere fluid as a reference system to provide the input reference bridge function leads to relatively good thermodynamics. However, at low temperatures the computed microscopic structure shows deficiencies that probably stem from the lack of orientational dependence in this bridge function...
In thermodynamics, chemical and biological kinetics, it is likely not possible to set this condition. Then an interesting and important case should be considered when the terminal time in Eq. (1.38) is not specified and is totally free (so-called free-end or open-end problem or natural ...

The current study develops an approachfor the optimization of an industrial HDPE slurry process with targetMWD. To exploit fully the advantages of nonlinear programming (NLP)algorithms, a complete equation-oriented (EO) model including rigorouskinetic mechanism, thermodynamics, and MWD calculation is ...

The law that entropy always increases—the Second Law of Thermodynamics—holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell’s equations—then so much the worse for Maxwell’s ...
A previously derived three-dimensional effective lattice theory describingthe thermodynamics of QCD with heavy quarks in the cold and dense region isextended through order $\\sim u^5\\kappa^8$ in the combined character and hoppingexpansion of the original four-dimensional Wilson action. The ...
This model was derived based on the statistical thermodynamics and is given by: (6.90)nKNittPe=θe1−θenexp−βθe where n is the number of occupied sites by an adsorbate. Also, KNitt and β are the Nitta isotherm constant and the interaction parameter, respectively. For the systems ...
aquifer and is affected by many different fluxes of matter, which are controlled by hydraulics (e.g., surface runoff and infiltration), thermodynamics, meteorology (precipitation, air temperature, wind, etc.), crops, orland cover(evaporation and evapotranspiration)....
