Select a material model to launch the closed cycle daemon.
PC Model
The working substance is a phase change (PC)
fluid. That is, it can exist as a sub-cooled liquid,
superheated
vapor, or as a mixture of saturated liquid and vapor. Example:
Steam is executing a closed cycle in a piston-cylinder device.
Gases:
PG Model
Obeys the ideal gas equation (pv=RT). Moreover, the specific heats are assumed constant. A perfect gas (PG) is a simplified ideal gas. Example:
Cold air standard Otto or Diesel cycle with specific heats assumed constant.
IG Model
Obeys the ideal gas equation (pv=RT). Specific heats are temperature dependent; thus, the IG model is more accurate than the PG model. Example:
Air standard Otto cycle with variable specific heats for better
accuracy.
n-IG Model
Create a mixture of upto sixty ideal gases, and use the resulting mixture as the working fluid of the closed cycle.
Diesel
Cycle
A closed cycle is a cyclic sequence of processes executed by a closed system (a trapped gas). For more examples of closed-cycles, visit VT.Chapter-7 pages.
