This reference illustrates the efficacy of CyclePad software for
enhanced simulation of thermodynamic devices and cycles. It
improves thermodynamic studies by reducing calculation time,
ensuring design accuracy, and allowing for case-specific analyses.
Offering a wide-range of pedagogical aids, chapter summaries,
review problems, and worked examples, this reference offers a
user-friendly and effective approach to thermodynamic processes and
computer-based experimentation and design. Thermodynamic Cycles
allows students to change any parameter and understand its effect
on device performance, run experiments and investigate results, and
run valuable sensitivity and cost-benefit analyses.
For the first time in power electronics, this comprehensive
treatment of switch-mode DC/DC converter designs addresses many
analytical closed form equations such as duty cycle prediction,
output regulation, output ripple, control loop-gain, and steady
state time-domain waveform. Each of these equations are given
various topologists and configurations, including forward, flyback,
and boost converters. Pulse Width Modulated DC/DC Converters begins
with a detailed approach to the quiescent operating locus of a
power plant under open-loop. The reader is then led through other
supporting circuits once again in the quiescent condition. These
exercises result in the close-loop formulations of the subject
system, providing designers with the ability to study the
sensitivities of a system against disturbances. With the quiescent
conditions well established, the book then guides the reader
further into the territories of system stability where small signal
behaviors are explored. Finally, some important large signal
time-domain studies cap the treatment. Some distinctive features of
this book include: *detailed coverage of dynamic close-loop
converter simulations using only personal computer and modern
mathematical software *Steady-state, time-domain analysis based on
the concept of continuity of states Voltage-mode and current-mode
control techniques and their differences of merits A detailed
description on setting up different equations for DC/DC
converters'simulation using only PC

This book and the accompanying computer software are intended to
enhance and streamline the study of the field of thermodynamics.
The package is design and problem-solving oriented. Released from
the drain of repetitive and iterative hand calculation, students
can be led to a far wider and deeper study than has been possible
previously.
Finite-time thermodynamics (FTT) is one of the newest and most
challenging areas in thermodynamics. The objective of this book is
to provide results from research, which continues at an impressive
rate. The authors make a concentrated effort to reach out and
encourage academic and industrial participation in this book and to
select papers that are relevant to current problems and practice.
The numerous contributions from the international community are
indicative of the continuing global interest in finite-time
thermodynamics. All represent the newest developments in their
respective areas.
Heat engines that use gases as the working fluid in a closed system
model were discussed in this book. Otto cycle, Diesel, Miller, and
Dual cycle are internal combustion engines. Stirling cycle is an
external combustion engine. The Otto cycle is a spark-ignition
reciprocating engine made of an isentropic compression process, a
constant volume combustion process, an isentropic expansion
process, and a constant volume cooling process. The thermal
efficiency of the Otto cycle depends on its compression ratio. The
compression ratio is defined as r=Vmax/Vmin. The Otto cycle
efficiency is limited by the compression ratio because of the
engine knock problem. The Diesel cycle is a compression-ignition
reciprocating engine made of an isentropic compression process, a
constant pressure combustion process, an isentropic expansion
process, and a constant volume cooling process. The thermal
efficiency of the Otto cycle depends on its compression ratio and
cut-off ratio. The compression ratio is defined as r=Vmax/Vmin. The
cut-off ratio is defined as rcutoff=Vcombustion off/Vmin. The Dual
cycle involves two heat addition processes, one at constant volume
and one at constant pressure. It behaves more like an actual cycle
than either Otto or Diesel cycle. The Lenoir cycle was the first
commercially successful internal combustion engine. The Stirling
cycle and Wicks cycle are attempt to achieve the Carnot efficiency.
The Miller cycle uses variable valve timing for compression ratio
control to improve the performance of internal combustion engines.
