sci.stirling-cycle-efficiency Calculator
Calculates Stirling engine theoretical efficiency and work output from hot and cold reservoir temperatures and regenerator effectiveness. Stirling cycle theoretical efficiency equals Carnot — unlike Otto/Diesel, it uses external combustion (any heat source) and a regenerator to recover waste heat.
Inputs
Hot Temp C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Cold Temp C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Regenerator Effectiveness
Reference formula or conversion factor shown for context.
Results
Stirling efficiency (practical)
Useful output divided by total input, as a percentage. True 100% efficiency is impossible — losses appear as heat. LEDs: 30–50%. Electric motors: 85–97%. Switching supplies: 85–95%.
