Working fluid for a thermodynamic cycle.

AI Thread Summary
A high thermal expansion coefficient liquid is sought for use as a working fluid in a thermodynamic cycle, specifically in the liquid phase throughout the process. Pentane has been identified as a suitable option, but further insights on alternative fluids or mixtures with advantageous properties are requested. Participants in the discussion are also exploring similar needs and applications for such fluids. The conversation highlights a shared interest in optimizing fluid selection for efficiency in thermodynamic systems. Additional expertise or experiences with various liquids is encouraged to enhance understanding.

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

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...
Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'
Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
