because there exists a series of mixing operations to obtain q→ from p→. That said, there are pairs of probability distributions where neither majorizes the other (here called incomparable), even though mixedness measures F are well-defined for both. This is because, for such incomparable pr...
Entropy-based metrics, such as the dilution index, have been proposed to quantify dilution and reactive mixing in solute transport problems. In this work, ... G Chiogna,M Rolle - 《Water Resources Research》 被引量: 0发表: 2017年 AN EMD AND IMF ENERGY ENTROPY-BASED OPTIMIZED FEATURE EXTRAC...
Thus, understanding the enthalpy and entropy of mixing is crucial due to the complexity of the alloying elements [47]. With the studies of some researchers, three rules on which the formation of solid solutions was established, namely: the enthalpy of mixing (ΔHmix), the entropy of mixing ...
A General Class of Lagrangian Smoothed Particle Hydrodynamics Methods and Implications for Fluid Mixing Problems Various formulations of smoothed particle hydrodynamics (SPH) have been proposed, intended to resolve certain difficulties in the treatment of fluid mixing...

S Q can be identified, in a way with the entropy of 'basis mixing'. The quantum evolution of a pure state is generally shown to be accompanied by an early loss of information followed by an information gain at a later stage. This happens irrespective of the adiabaticity or the lack of...
A special case of entropy increase, theentropy of mixing, occurs when two or more different substances are mixed. If the substances are at the same temperature and pressure, there will be no net exchange of heat or work – the entropy change will be entirely due to the mixing of the diff...
According to the Hume-Rothery rules, the incorporation of solute atoms into a multicomponent solid solution will not disturb the crystal structure of the parent phase. Therefore, it is believed by some that the mixing enthalpy of high-entropy alloys, in addition to the atomic size difference and...
s volume. If the thermodynamic fluxes and forces are constant in space, then the total entropy production differs from the local production only by a factor equal to the volume of the system. The relation between the fluxesJiand the thermodynamic forcesxiproducing the fluxes is given by the ...
thermal conductivity and fins structure. It is noted that entropy generation for a decay exponential fin is higher than that of a rectangular fin which is greater than that of a growing exponential fin. Moreover, entropy generation decreases as thermal conductivity increases. The results also reveal...
For equimolar alloys, this equation reduces to DScmoinxf ¼ RlnðnÞ, where n is the number of elements. This simple relationship between the configurational entropy of mixing and the number of principal elements serves as the basis for defining high-entropy alloys as having five or more ...
