Entransy Concept and Controversies: A Critical Perspective within Elusive
Thermal Landscape

Abstract (See attached full paper - PDF file below, and Kostic to attend
IHTC-16):

The concept of ‘entransy’, a product of heat and temperature, originally called
‘heat transport potential capacity’, was introduced in 2003, as analogy to
product of electrical charge and voltage, as well as other similar quantities.
The concept has been extended to entransy property, as integral product of
‘stored heat’ and temperature, MCvT2/2, thus representing quantity and quality
of stored heat, or thermal energy in isochoric processes without work
interactions. The entransy has been used for analysis and optimization of many
heat transfer processes as described in many publications since its
introduction, and is under further development. Later, the entransy concept has
been criticized and denounced by a group of researchers, thus creating
controversies that need to be put in a broader, historical and contemporary
perspective, which is the main goal of this paper. Despite the need for further
clarifications and development of the new concept, it would be premature and
unjust to discredit entransy, based on limited and subjective claims, as if the
‘already established’ concepts and methodologies are perfect, and do not need
alternatives and innovations, as if further progress is not needed.

Keywords: Entransy, Entropy, Exergy, Heat, Thermal energy, Carnot work
potential.
