NIST REFPROP 9 holds a special place in engineering history. It arrived during a transition period where computing power was finally sufficient to run full Helmholtz equations in real-time on a desktop PC. It democratized access to reference-quality data, moving it from national labs to small engineering firms.
: REFPROP 9 can calculate properties for mixtures with up to 20 components, utilizing models like the Tillner-Roth and Friend correlation for ammonia-water systems. nist refprop 9
Version 9 represented a significant leap forward in fluid modeling. Here are the standout features that made this version a staple in the engineering industry: NIST REFPROP 9 holds a special place in engineering history
One of REFPROP’s strongest selling points is its ability to handle mixtures. REFPROP 9 allows users to define mixtures of up to 20 components. This is vital for industries dealing with natural gas processing or custom refrigerant blends. The software uses advanced mixing rules to predict how these different molecules interact, providing accurate phase-envelope data. : REFPROP 9 can calculate properties for mixtures
REFPROP (short for ) is a software program developed by the National Institute of Standards and Technology (NIST) . It provides thermophysical properties of pure fluids and mixtures, based on the most accurate equations of state available.
