The performance and thermal properties of convective–radiative rectangular and moving exponential porous fins with variable thermal conductivity together with internal heat generation are investigated. The second law of thermodynamics is used to investigate entropy generation in the proposed fins. The model ...

Taking advantage of the analogies between electromagnetism and thermodynamics, some researchers developed materials with unprecedented thermal properties (the thermal "metamaterials") for heat flux manipu- lation, for instance the heat flux inverter by Narayana and Sato2. Compared to the advances in ...
in physics, the specific heat is the important thermodynamics property. it is defined as the amount of heat per unit mass needed to raise the temperature by one degree celsius. the specific heat value can have a varying range for different substances depending on the extent to which the ...
“Design of a branched heat exchanger” is a much simpler engineering exercise, based on diligent scientific considerations, and a small number of prime principles in fluid- and thermodynamics suffice to concoct a sufficiently accurate preliminary design that is as “optimal” as needed. This happens...
Engineering Thermal Properties of Metals, Conductivity, Thermal Expansion, Specific Heat Data - Metals in general have high electrical conductivity, high thermal conductivity, and high density. Typically they are malleable and ductile, deforming under st
The Crocco theorem is obtained in a fluid vortex flow field based on the first law of thermodynamics, that is, conservation of energy. The theorem quantitatively expresses a relationship among a gradient of thermodynamic enthalpy, a gradient of entropy and swirling intensity of the vortex flow in...
Guyer-Krumhansl (G-K) equation is a promising macroscopic model to explore heat transport in nanoscale. In the present work, a new nonlocal characteristic length is proposed by considering the effects of heat carriers-boundaries interactions to modify th
