Working fluid for a thermodynamic cycle.

Click For Summary
SUMMARY

The discussion centers on identifying a suitable working fluid for a thermodynamic cycle that remains in the liquid phase throughout the process. Pentane is highlighted as a leading candidate due to its high thermal expansion coefficient. Participants are also interested in exploring potential mixtures of liquids that may exhibit desirable thermal properties for this application. The conversation emphasizes the need for expert insights on fluid selection and mixtures.

PREREQUISITES
  • Understanding of thermodynamic cycles
  • Knowledge of thermal expansion coefficients
  • Familiarity with fluid properties and behavior
  • Experience with fluid mixtures and their applications
NEXT STEPS
  • Research the thermal properties of pentane and its applications in thermodynamic cycles
  • Investigate alternative working fluids with high thermal expansion coefficients
  • Explore the effects of liquid mixtures on thermal performance
  • Study the design considerations for thermodynamic systems using liquid-phase working fluids
USEFUL FOR

Engineers, researchers, and students involved in thermodynamics, particularly those focused on fluid selection and system design for thermal applications.

I am looking for a liquid with a high thermal expansion coefficient. This liquid should act as a working fluid in an thermodynamic cycle based on a system where the working fluid act in the same phase (liquid phase) throughout the cycle.

So far I have found pentane as one of the most suitable fluids - but I would like to know if there are people with experience / knowledge that can help me in this case.

For instance if there exist mixtures of different liquids with special properties that can be interesting?

Thank you.

Hey Geir,

I am actually trying to find some info on the same type of fluid? Did you have any luck? what application were you using it for?

Thank you
