Introduction to Vapor and Gas Power Cycles
Now that we understand the 1st and
2nd Lawsof Thermodynamics we can consider some important applications and the equipment used to generate mechanical power from heat. In this chapter, we will consider
power cyclesand in the next chapter we will discuss
In this chapter, we will study both
gas power cyclesin greater detail and consider how their performance can be improved.
During the cycle the working fluid exists as a vapor for part of the cycle and a liquid for the other part. Key components include a condenser and a boiler.
During the entire cycle the working fluid remains in the gas phase. No phase changes occur.
After each pass through the cycle, the working fluid remains within the system.
In an open cycle, one heat exchanger is missing. After the working fluid passes through three processes, it is discarded and replaced by fresh working fluid.
