Development in classical thermodynamics is, logically and traditionally,
aimed at the analysis of cycles. Computational efforts impose harsh
constraints on the kinds and amounts of cycle analyses that can reasonably
be attempted. Cycle simulations cannot approach realistic complexity. Even
relative sensitivity analyses based on grossly simplified cycle models are
computationally taxing compared to their pedagogical benefits.
The desire for more design content in thermodynamic books is a
familiar theme emanating from engineering industry and educational
oversight bodies. Thermodynamic cycles are fertile ground for engineering
design. Niches for innovative power generating systems for example, are
being created by deregulation, cogeneration, vacillating fuel costs, and
concern over global warming. Computerized look-up tables reduce
computational labor somewhat, but modeling cycles with many interactive
loops still lies well outside of power-engineering time budgets.
This book is based on intelligent computer software called Cyclepad.
Cyclepad was developed by Professor K. Forbus of Northwestern University
and evaluated by me. It is a powerful, mature, user-friendly freeware package
developed expressly to simulate thermodynamic devices and cycles. It
reduces by about 100-fold the computational effort involved in modeling
realistically complex systems and cycles. It thus makes it feasible for
engineers to run meaningful sensitivity analyses, to consider combinations
of design modifications, to make engineering cost–benefit analyses, and to
include refinements such as accounting for pressure changes and heat
transfers occurring between major cycle components.
A previous book of mine (Intelligent Computer-based Elementary
Applied Thermodynamics, 2002) covers the basic concept and laws of
thermodynamics.
This book, along with Cyclepad, is intended to comprise the cycle
portion in thermodynamics or to support cost–benefit analyses and to
direct design projects. It is strictly design- and problem-solving oriented. |
