Results visualization
After the cycle's programming is performed within the macro @solve, the results can be presented through tables and graphs by calling the PrintResults() function.
Visualization properties
For a better visualization of the system's graph, it's possible to add some attributes in its generation, modifications to the PrintResults() function, which is composed of two optional attributes: PrintResults(graphs=1, showStateNames=true, multiplyEntropyByMass=false).
graphs: Defines which graphs will be displayed according to the number entered:- Shows T-s graph.
- Shows P-h graph.
- Shows T-s and P-h graphs.
showStateNames: Defines if the names of the states appeared in the generated T-s graphs.
multiplyEntropyByMass: Defines if the cycle entropies will be multiplied by their mass flow.
Access to properties
To access the resources for analyzing and manipulating data related to thermodynamic cycles, you can use the CycleSolver.SystemCycles command to obtain the list of cycles.
Each cycle has specific thermodynamic properties that can be accessed. For example, to obtain the thermodynamic properties of the cycle at index 1, simply use CycleSolver.SystemCycles[1].thermoProperties. Within these properties, you can access information such as the heat transfer into the cycle, represented by CycleSolver.SystemCycles[1].thermoProperties.qin, and the cycle efficiency, accessed with CycleSolver.SystemCycles[1].thermoProperties.n.
Furthermore, each cycle is composed of a series of thermodynamic states. To view the list of states in the cycle at index 1, the command CycleSolver.SystemCycles[1].states is used.
To access the specific properties of each state, in addition to the syntax presented earlier, it is also possible to obtain the properties with the command CycleSolver.st1, which provides access to the properties of the state identified as st1. To view the enthalpy of this state, simply use CycleSolver.st1.h.
It is important to note that if there is more than one cycle, in addition to the individual properties of each cycle, there will also be properties related to the system of cycles as a whole. These properties can be accessed through the command CycleSolver.System. The heat transfer into the system can be viewed with CycleSolver.System.qin, while the system efficiency is obtained through CycleSolver.System.n.
Energy/Mass Imbalance and Entropy Generation
To visualize the Energy/Mass Imbalance and Entropy Generation, the PrintImbalance function is used, which displays these properties for each component and for the system. To access these properties through code, you can use the variable CycleSolve.SystemImbalanceAndEntropyGeneration, which is a list with three values, representing respectively, the Energy Imbalance, Mass Imbalance, and Entropy Generation.
