Geothermal Energy & Organic Rankine Cycles
Thermodynamics
PhD-level geothermal engineering and power cycle analysis: geothermal resource classification, single-flash and binary ORC cycle thermodynamics using second-law (exergy) analysis, working fluid selection criteria (critical temperature, ODP, GWP, flammability), turbine design constraints, and brine reinjection for sustainability of hydrothermal systems.
Learning Objectives
- Classify geothermal resources by temperature and describe suitable power conversion technologies for each class
- Analyse single-flash steam cycles using enthalpy–entropy diagrams and compute specific work output and efficiency
- Apply exergy analysis to quantify irreversibilities in each component of a binary ORC
- Select ORC working fluids based on thermodynamic fit, environmental impact, and safety constraints
- Compute the Carnot and practical ORC efficiency bounds and the exergetic efficiency for a given heat source
