Volume 11: Thermal Sciences for Engineers

 

 

 

 

 

 

 

Thermal science is a ternary subject that comprises thermodynamics, fluid mechanics and heat transfer. Noting that thermodynamics is energy transformation, fluid mechanics is energy transportation, and heat transfer is movement of energy due to temperature differences, it is quite easy to see that in almost all engineering applications these three sciences occur simultaneously. The biggest shortcoming faced by engineers is to treat each subject separately without seeing how they interact.

The key objective of this book is firstly to present the three key disciplines, viz. thermodynamics, fluid mechanics and heat transfer, that influence the technical part of the generating and new build businesses. More importantly, the application of the essential theory to operating plant and new designs is discussed using language familiar to Eskom engineers. To an extent, examples are provided where engineering judgement is needed, and guidelines to resolve such incidents are provided.   

 
Applications of thermal sciences in practice, where energy transformation, transportation and heat transfer occur is presented under the topic of field applications. These examples include the development of a theory that could be used to cast better quality turbine blades; wind turbine technology; the development of the Betz limit (likened to the Carnot efficiency) together with the analysis of wind data, which includes topics such as turbulence intensity and wind velocity profiles; and finally the use of atmospheric radiation to generate power in central receiver systems. In the final example, the basic equations are developed using vector theory and encoded in an Excel-based code called SOLAR (developed by the author). SOLAR is used to determine the heliostat field cosine efficiency as a function of date and time of day. A design example on the determination of the receiver wall thickness and the maximum receiver temperature is also presented to the reader.
 
It is the author’s wish that, besides having the book become a desktop reference, the reader internalises the contents of the book before attempting designs or design reviews. The book will serve as a refresher for the engineer that has been out of touch with the subject matter for a while, and as a learning tool to the trainee engineer.
