1. Entropy Generation Minimization

2. EGM Also called Optimization of devices with imperfections due to
Thermodynamic Optimization
Finite time thermodynamics (in Physics)
Optimization of devices with imperfections due to
Heat transfer
Mass transfer
Fluid flow
Other transport processes

3. EGM Objectives depend on application
Heat exchangers – minimization of entropy generation
Power plants – maximize power output
Refrigeration – minimize power input

4. EGM Common treatment (real processes) Feature rate processes
Finite size of devices
Finite times
Finite speeds
etc.

5. EGM To minimize entropy generation rate Need expression of sgen
Need ΔT ↔ Qdot relations
Need ΔP ↔ mdot relations
All details (thermos, heat transfer, fluid mech), finite time, finite size
Modify design and see how sgen changes
