This book deals with two chapters: Psychrometrics and Reactive systems.
Under Psychrometrics, which is the study of properties of air-water vapor mixtures, we, first give the definitions of various terms and also the thermodynamic equations to determine various psychrometric properties. Then, some psychrometric processes adopted in air-conditioning are explained with the help of Psychrometric chart. Two very good stand-alone calculators to quickly calculate various Psychrometric properties are explained.
Several very useful Functions are written in Mathcad to calculate various psychrometric properties. A summary of the Mathcad Functions written is also provided.
Under Reactive systems, basically, we deal with combustion. Combustion equations and their balancing by atoms of constituents is presented.
Stoichiometric Air-Fuel (AF) ratio, actual AF ratio, percent excess air, equivalence ratio etc are explained. Enthalpy of formation of compounds, enthalpy of combustion or enthalpy of reaction are explained.
Tables of enthalpies of formation and other tables for enthalpies of different species required for combustion calculations are presented.
Heat transfer during combustion and Adiabatic flame temperature are explained.
Also, many useful functions are written in Mathcad and EES and several problems are solved using Mathcad, EES and TEST to illustrate the problem solving techniques in both the chapters.

This book deals with two important chapters in Applied Thermodynamics, viz. “Cycles for Gas Turbines and Jet propulsion” and “Vapor power cycles”.
Brayton cycle is the air standard cycle for Gas Turbines. Modifications to the Ideal Brayton cycle to increase the thermal efficiency are also studied; these include adding a regenerator and resorting to multistage compression in the compressor and multistage expansion in the turbine.
Jet propulsion cycle used for aircraft propulsion is also analysed.
Several Functions/ Procedures are written in Mathcad and EES to determine network, thermal efficiency etc of the Ideal and actual Brayton cycles.
“Vapour Power cycles” are analyzed with particular reference to Ideal Rankine cycle and its variations, used in Steam Power Plants.
Several useful Mathcad Functions are written for properties of steam in superheated and two-phase regions, since Mathcad does not have built-in Functions for steam, and these will be extremely useful in solving problems on Rankine cycle.
Also, many useful Functions/Procedures are written in EES for different variations of Rankine cycle.
In both these chapters, problems from University question papers and standard textbooks are solved with Mathcad, EES and TEST.

his is Part – I of the book: “Applied Thermodynamics: Software Solutions”.
This is a logical continuation from the book “Basic Thermodynamics: Software Solutions”, published earlier.
In this book, problems on ‘Gas power cycles’ are solved.
Cycles dealt with are: Carnot cycle, Otto cycle (for petrol engines), Diesel and Dual combustion cycles (for Diesel engines) and Stirling cycle.
Software used are: Mathcad, Engineering Equation Solver (EES), and The Expert System on Thermodynamics (TEST).

This is Part–V of the book: “Basic Thermodynamics: Software Solutions”.
Here, Real and Ideal gases and Gas mixtures are dealt with.
Very useful information on Real and Ideal gases and Equations of state are compiled.
Other topics covered are: ‘compressibility factor’ and ‘principle of corresponding states’, Internal energy, Enthalpy and Specific heats for Ideal gases, properties of mixtures of ideal gases. Dalton’s Law, Gibbs-Dalton Law, Avogadro’s Law etc are stated. Procedures to calculate sp. heats, apparent Molecular weight, Gas constant, internal energy, enthalpy etc of a mixture of ideal gases is explained.
A very useful EES Function to determine Compressibility factor, Z when reduced temp, Tr and reduced pressure, Pr are given, is given in Appendix of chapter 9, and its use is explained with an example.
Above topics are illustrated by solving several problems using Mathcad, EES and TEST software.

This book contains three chapters, viz. Refrigeration cycles, Air compressors and Thermodynamic relations:
1. Under ‘Refrigeration cycles’, following cycles are analyzed: Ideal and actual vapour compression cycle, Ideal and actual reversed Brayton cycle (or, Bell Coleman cycle). Several useful Mathcad Functions are written for properties of Refrigerant- R134a in superheated and two-phase regions, which are used in solving problems. Also, useful Mathcad Functions are written to facilitate easy calculations for all these cycles. And, many useful Functions/Procedures are written in EES for different variations of ideal vapor compression refrigeration cycle.
2. Under ‘Air compressors’, reciprocating air compressors (both single stage and multi-stage) are analyzed. Formulas to calculate various parameters such as: volumetric efficiency, work required for actual compression, isothermal efficiency, minimum work required for two- stage (or multistage) compression with perfect inter-cooling etc. are presented.
3. Under ‘Thermodynamic relations’, relations are presented to calculate ‘Thermodynamic properties’ which are impossible or difficult to measure (such as: entropy, internal energy, enthalpy, Helmholtz function and Gibbs function), in terms of measurable quantities such as pressure, volume and temperature. Topics dealt with are: Maxwell’s equations, TdS equations, heat capacity relations, energy equations, Joule – Kelvin effect, Clausius - Clapeyron equation etc. which are practically important.
4. In these chapters, problems from University question papers and standard Text books are solved with Mathcad, EES and TEST.

This book is written to introduce the basics of computational fluid dynamics including turbulence modelling. The book contains three parts: basic computational fluid dynamics (CFD), turbulence modelling and application of CFD to some selected problems of human thermodynamics. The idea of the first part is to describe different numerical methods and algorithms in a simple manner and to enable the readers to write their first CFD programs. The aim of the second part is to cover fundamental aspects of turbulence modelling starting from the physics and principles of the statistical description of turbulence. A short introduction to basic CFD models based on Reynolds averaging and Large Eddy Simulation is given in a clear and simple form. The last part of the book is devoted to the application of CFD to various problems connected to interaction between human body and surrounding medium. The book can be used for lecture courses on CFD, turbulence modelling and applied human thermodynamics.

This book, viz. “Applied Thermodynamics: Software solutions – Vapor Power cycles (Rankine cycle)” is a supplement to the Part-II of the popular, free ebook series on Applied Thermodynamics: Software Solutions by the same author, published by Bookboon.
Rankine cycle and its variations are used in Steam power plants, marine applications etc.
In this book, as with other books of this series, the focus is on the solutions to problems using computer software. Only the essential theory and summary of equations required for calculations are given at the beginning of the chapter.
Here, we have particularly focused on solving problems with the very useful software, Mathcad.
Since Mathcad does not have built-in functions to determine the properties water/steam, we have first written useful functions for properties of water/steam using data from NIST. Then, we demonstrate the ease with which one can do calculations, produce tables and graphs of results, and perform ‘what – if analysis’ with Mathcad, by solving a variety of problems.
Several Functions are written in Mathcad to simplify the standard and most often required calculations for Rankine cycle and its variations, which, the students, teachers, researchers and professionals may find very useful.
Mathcad programs are given clearly and transparently, so that those who need them can use them for their works.
S. I. Units are used throughout this book. Wide variety of worked examples presented in the book should be useful for those appearing for University, AMIE and Engineering Services examinations.
