Components and Thermodynamic Cycles
Although many technical components, that are required to run energy conversion processes, have already been discussed previously, the focus in this chapter is on thermal turbo-machines as well as on heat exchangers. However, in this chapter the technical components are treated in steady state operation. In order to quantify the efficiency of turbine and compressor the so-called isentropic efficiency is defined. In addition, relevant thermodynamic cycles are introduced and discussed. Cyclic processes have been discussed in the previous chapters as well, but mostly in a black-box notation. A distinction has been made between clockwise cycles, i.e. thermal engines, and counterclockwise cycles, i.e. cooling machines respectively heat pumps. This chapter concludes the first part of this book.
