Thermodynamics Workshop — Cycle Analysis, First & Second Law Evaluation & Performance Benchmarking

Structured thermodynamic analysis of engineering power and refrigeration cycles: first- and second-law energy balances applied to idealised and real systems, entropy generation quantified at each process step, cycle thermal efficiency mapped against the idealised Carnot benchmark, and thermodynamic property tables used to evaluate state-point conditions across a range of operating parameters — with attention to identifying where irreversibilities arise and how they limit practical cycle performance.

Cycle Modelling & State-Point Analysis
  • Evaluated thermodynamic state points for each process in the cycle using fluid property tables, correctly reading saturation and superheated property data and interpolating where required.
  • Applied steady-flow energy equations at each component (turbine, pump, boiler, condenser, compressor) to determine work and heat interactions per unit mass, maintaining sign convention consistency throughout.
  • Computed cycle thermal efficiency from net work output and heat input, then benchmarked the result against the Carnot limit operating between the same thermal reservoirs to quantify the irreversibility penalty.
Second Law & Irreversibility Analysis
  • Calculated entropy generation at each process step, distinguishing reversible (isentropic) processes from real ones and using entropy change to identify where cycle losses are concentrated.
  • Applied second-law efficiency metrics to separate the thermodynamic potential available from a heat source from the fraction actually converted to useful work, quantifying the exergy destruction at major components.
  • Assessed the impact of parameter variation (operating pressure, superheat degree, condenser temperature) on cycle efficiency and specific work output, identifying design trade-offs between net output and thermal efficiency.
  • Compared ideal cycle assumptions against realistic device behaviour, discussing how isentropic efficiencies of turbines and compressors shift cycle performance and degrade second-law efficiency.
