Thermophysical Properties and Heat Transfer Using Nanofluids: a Review

Authors: Enrique Marcet Garcia, Eddy Martinez Padron, Marcelo Marcet Sanchez
Comments: 26 Pages.

Nanofluids are considered to offer significantly more advantages in heat transfer than conventional fluids. Recently theoretical and experimental research papers appeared in the literature on thermophysical properties of nanofluids and enhancement of heat transfer using suspensions of nanoparticles. The aim of this review summarizes the results of research papers about thermophysical properties and forced convection heat transfer with nanofluids.

Thoughts on Negative Heat Capacities

Authors: Jeremy Dunning-Davies
Comments: 10 Pages.

By referring to well-established deductions from the Second Law of Thermodynamics and to the fact that concavity is the essence of this law, it is shown that the existence of negative heat capacities for closed systems is incompatible with the Second Law. However, it is seen that the heat capacity of an open system could be negative.

On the Statistical Nature of the Second Law of Thermodynamics

Authors: Jeremy Dunning-Davies
Comments: 5 Pages.

It is intended here to consider the Second Law of Thermodynamics and various deductions made from it, especially the introduction of the quantity known as the entropy. The starting point will be the formulations of the law in classical thermodynamics. Attention will then move to so-called statistical thermodynamics to help illustrate the point that the Second Law of Classical Thermodynamics is certainly not statistical in nature.
