Energy conversion doctrine The doctrine of MTH—which is based on the
interconvertibility principle and the energy principle, both of which are
self-evident propositions—that “everything that happens is the result of energy
and its transformation from one form to another.” It is the doctrine serving as the
cornerstone of the MTH version of engineering thermodynamics. As self-evident
truth, it captures a part of truth but it turns out to be incoherent and contradictory
on the whole.
The energy principle Mechanical energy dissipates universally into heat;
high-grade energy dissipates into lower-grade energy without limit;
phenomena of entropy growth are exhausted by energy-dissipation phenomena.
Entropy growth potential Entropy growth potential (EGP) is the driver of every
event in a given Poincare range (See Sect. 8.5).
Entropy growth potential principle Every event in a given Poincare range shares
the same EGP Poincare-range , therefore, EGP Poincare-range is the driver of every event
of the range, therefore, general EGP is the driver of all events in nature.
EGP-centric doctrine The doctrine of PETH, which refutes interconvertibility
principle and considers that the energy principle is subsumed under the entropy
growth potential principle. Furthermore, it denies the existence of pure reverse
energy transformation asserting that any reverse energy transformation is an
element of a triadic process consisting of EGP the driver, heat from heat
reservoir, and energy in useful form, e.g., mechanical energy.
The entropy principle Entropy change of an isolated system (universe), which
undergoes certain process, is never negative. That is, entropy change is always
positive (entropy always growths) or equal to zero (in case of reversible change).
Equilibrium thermodynamics A branch of thermodynamics, also known as
Gibbsian thermodynamics, that is based on the entropy principle as its
centerpiece rather than the problematic energy principle or the energy
conversion doctrine. That being the case, equilibrium thermodynamics, unlike
engineering thermodynamics, is a coherent branch-system of theoretical physics.
Exergy Exergy is the portion of energy that is entirely convertible into all other
forms of energy, i.e., convertible to mechanical energy (which can be converted
into all other forms without limit). This is one definition of exergy, see Sect. 7.3
for the other definition.
First law of thermodynamics Energy can neither be created nor destroyed.
Form of energy Forms of energy include heat (thermal energy), light, electrical,
mechanical, nuclear, sound and chemical.
Heat Energy and entropy in transit, or, a high-entropy form of energy related to its
temperature (thermal energy).
