NIST Reference Fluid Thermodynamic and Transport Properties Database

REFPROP Version 10 calculates thermodynamic and transport properties for industrially important fluids and mixtures using models from the National Institute of Standards and Technology. The software implements three primary models for pure fluids: equations of state explicit in Helmholtz energy, the modified Benedict-Webb-Rubin equation, and an extended corresponding states model. It was last updated in July 2022.

Use Cases

• Calculate pure fluid properties like density or enthalpy using the Helmholtz energy, modified Benedict-Webb-Rubin, or extended corresponding states models.
• Model mixture properties by applying mixing rules to the Helmholtz energy of components and using a departure function for non-ideal mixing.
• Estimate transport properties such as viscosity and thermal conductivity using fluid-specific correlations, the ECS method, or friction theory.
• Integrate property calculations into user applications via the REFPROP dynamic-link library for process simulation.

Strengths

• Developed by the National Institute of Standards and Technology, a leading authority on measurement science.
• Implements three distinct, high-accuracy thermodynamic models for pure fluid property calculation.
• Models transport properties like viscosity with multiple methods including fluid-specific correlations and ECS.
• Last updated in July 2022, indicating recent maintenance.
