In this report, we describe an extended corresponding states model for viscosity and thermal conductivity of mixtures implemented in version 8 of the NIST computer program REFPROP. The model is a modification of a one-fluid, extended corresponding states (ECS) model for thermal conductivity and viscosity originally developed by Ely and Hanley (Ind. Eng. Chem. Fundam., 1981, 20:323-332). We apply the model to selected mixtures representative of the fluids available in the NIST 23 database REFPROP (v8) such as refrigerants and natural gas constituent fluids, and present comparisons with experimental data. Comparisons are given for both gas, liquid, and supercritical conditions.

This paper investigates the effect that the bulk lubricant concentration has on the non-adiabatic lubricant excess surface density on a roughened, horizontal flat pool-boiling surface. Both pool boiling heat transfer data and lubricant excess surface density data are given for pure R134a and three different mixtures of R134a and a polyolester lubricant (POE). A spectrofluorometer was used to measure the lubricant excess density that was established by the boiling of a R134a/POE lubricant mixture on a test surface. The lubricant is preferentially drawn out of the bulk refrigerant/lubricant mixture by the boiling process and accumulates on the surface in excess of the bulk concentration. The excess lubricant resides in an approximately 40 mm layer onthe surface and influences the boiling performance. The lubricant excess surface density measurements were used to modify an existing dimensionless excess surface density parameter so that it is valid for different reduced pressures. The dimensionless parameter is a key component for a refrigerant/lubricant pool boiling model given in the literature. In support of improving the boiling model, both the excess measurements and heat transfer data are provided for pure R134a and three R134a/lubricant mixtures at 277.6 K. The heat transfer data shows that the lubricant excess layer causes an average enhancement of the heat flux of approximately 50 % for the 0.5 % lubricant mass fraction mixture relative to pure R134a heat fluxes between 4 kW/m2 and 20 kW/m2. Conversely, both the 1 % and the 2 % lubricant mass fraction mixtures experienced an average degradation of approximately 60 % in the heat flux relative to pure R134a heat fluxes between approximately 4 kW/m2 and 20 kW/m2. This study is an effort toward generating data that can be used to support a boiling model that can be used to predict whether lubricants degrade or improve boiling performance.

This publication provides guidelines for evaluating data from advanced mass calibrations and for establishing measurement assurance programs in precision mass calibration laboratories. The NIST Weights and Measures Division (WMD) will use these guidelines when evaluating advanced mass calibration data for State laboratories that request technical support, Recognition, and/or National Voluntary Laboratory Accreditation Program (NVLAP) accreditation.Advanced mass calibrations use weighing designs, such as those found in NBS Handbook 145 (SOP 4, 5), NISTIR 6969, Selected Publications, NBS Technical Note 952, and the NIST/SEMATECH e-Handbook of Statistical Methods that require the use of computer software (mass code) for the data reduction. These weighing designs are normally used when high precision (low uncertainty) mass measurement results are sought, although weighing designs can be used at any uncertainty level. The uncertainty reported using advanced weighing designs is based on the historically observed process of similar measurements and is very dependent upon correct procedures for defining these processes.
