While the equation for efficiency is found using the first law of thermodynamics, the American Physical Society study “Efficient Uses of Energy” points out that the second law of thermodynamics, which shows that the Carnot engine operating between two temperatures is the most efficient, allows us...
K.Behnia, inEncyclopedia of Condensed Matter Physics (Second Edition), 2024 Definition Heat travels inside solids due to a property calledthermal conductivity. The magnitude of thermal conductivity is specific to each element, alloy, or compound and is defined by the equation relating the heat flow...
The evolution of the growing surface waves having a nonuniform transversal structure is discussed using the semiempirical equation for wind velocity profil... LS Tsimring,PAEM Janssen - 《Journal of Physical Oceanography》 被引量: 1436发表: 1993年 The initial stage of sintering for the W–Cu nan...
If equation (2) or (3) or alternative universal relations hold,αmeasured in a glass or liquid would allow one to predict glass temperatures, without any knowledge of microscopic pair potential parameters. At the same time, one could gain insight into the universality of configurational contributio...
We study the equation of state of a strongly interacting theory of relativistic bosons and chiral fermions in the vicinity and above the chiral phase-trans... J Braun - 《Physical Review D Particles & Fields》 被引量: 64发表: 2010年 Molar Volume and Thermodynamics of the Structural Change of...
4. Above approximately room temperature, the temperature dependence of squared frequency can be rationally fitted by equation Ωq(T)=a(T−Tc)235, where Tc is the phase transition temperature. Applying the above equation, we obtain the phase transition temperature Tc as 83 K....

Four LWR benchmark problems in X-Y geometry are calculated using the ''Surface Flux'' transport code SURCU based on the solution of the integral transport equation. Quadruple spherical harmonics (QPN), orthogonal in angular quadrants, are used to approximate the incoming and outgoing surface fluxe...
Eb is called the emissive power of a black body. The term “black body” should be taken with caution for although most surfaces which look black to the eye are ideal radiators, other surfaces such as ice and some white paints are also black at long wavelengths. Equation (15) is known ...
In the past few years, the theory of thermal transport in amorphous solids has been substantially extended beyond the Allen-Feldman model. The resulting formulation, based on the Green-Kubo linear response or the Wigner-transport equation, bridges this m
