This third book in the Thermodynamics series focuses largely on applications in the field. Typically, when making a decision, sparse information is available to the engineer. In this instance, some engineering judgement is required and, with the aid of proper tools, a decision can be made speedily. To assist in the decision making the author has compiled six apps that the author felt would be applicable to an engineer practising in the power generation environment. These apps include ‘PipeFlow’, ‘Engine’, ‘SteamPlant’, ‘WindAnalyse’, ‘SolarAngles’ and ‘SolarC This third book in the Thermodynamics series focuses largely on applications in the field.

In this instance, some engineering judgement is required and, with the aid of proper tools, a decision can be made speedily. To assist in the decision making the author has compiled six apps that the author felt would be applicable to an engineer practising in the power generation environment.

 In each chapter the fundamental theory is revised/discussed before the app is introduced. The app is intended to be simple and user friendly and is ideal for use when desktop work is undertaken. A brief explanation of each app is given below.    

 
Pipe
Flow: Used for the analysis of simple and complex flow including work transfer and major and minor losses. The tool is ideal for use by engineers at the basic design level where losses are required to determine electrical loads for pumping, etc. The app may also be used to consider a site for, say, pumped storage. Examples are provided to explain use in this environment.
 
Engine: This app is used for all gas turbine and gas/diesel engine plant at the concept/basic design level where perhaps the power output is required for a certain fuel source or the fuel energy is required for a desired power output. In addition, the app calculates the fuel cost for gas and liquid fuel based on a user input fuel cost in ZAR/GJ and ZAR/L respectively. Combined cycle analysis is included in the app.
 
SteamPlant: In this app, the steam plant power output is calculated based on a coal specification that includes an analysis of the coal and volatiles as well as the ash. The calorific value of the coal sample is calculated and the effect of using wet coal is clearly demonstrated as far as the plant output is concerned.
 
WindAnalyse: This app takes raw data as received from site and does a comprehensive and complete analysis of the data in a single step and is in full compliance with IEC 61400-1. The tool is indispensable to any user who is at the phase of performing wind resource analysis and does not have bespoke software, such as Windfarmer.
 
SolarAngles: The highly complicated algorithm devised by National Renewable Energy Laboratory is encoded into Visual Basic for use in the EXCEL environment. This app produces an accurate output for the solar azimuth and zenith angles based on a time, date, day, month and year input for a specific location, elevation, site temperature and pressure. The app is similar in terms of interface to the app ‘Solar1’ written by the author.
 
SolarCSPDesign: For a given Direct Normal Irradiation (DNI) value and desired plant output, this app generates the heliostat number as well as the total tower base thermal power required for a solar multiple. It is a simple yet powerful app that is indispensable at the concept/basic design phase of the project. One may use this app to perform, say, a parametric analysis before putting out an enquiry for the most efficient salt-water/steam heat exchanger, by increasing the efficiency of the heat exchanger and observing the effect on the number of heliostats.
