I thank Professor Mark A. M c Hugh for his guidance throughout my undergraduate and graduate education. Dr. M c Hugh's guidance has truly been a significant factor in my growing love for the field of chemical engineering. Lastly, I would like to note that Dr. M c Hugh has never failed to keep me entertained and inspired through his lectures. It has been a pleasure working with Dr. M c Hugh. I would also like to thank Dr. Reddy Mallepally for working closely with me and teaching me how to perform high-pressure experiments. I appreciate Dr. Mallepally's guidance as it has been an integral part of my development as a researcher. In addition, I thank Dr. Babatunde Bamgbade for always lending a helping hand and offering me additional advice from his previous experiences.
The development of reference correlations for viscous fluids is predicated on the availability of accurate viscosity data, especially at high pressure, high temperature (HPHT) conditions. The rolling ball viscometer (RBV) is a facile technique for obtaining such HPHT viscosity data. A new, universal RBV calibration methodology is described and applied over a broad T-p region and for a wide range of viscosities. The new calibration equation is used to obtain viscosities for n-hexadecane (HXD),
Bubble
point pressures of six binary mixtures at two compositions
each have been measured utilizing a static method. The performance
of the apparatus was characterized from bubble point measurements
of R32 + R125 for which 19 literature studies are available for comparison.
The mixtures studied were as follows: R1234yf + R134a, R134a + R1234ze(E),
R1234yf + R1234ze(E), R125 + R1234yf, R1234ze(E) + R227ea, and R1234yf
+ R152a. For each mixture, measurements were conducted from 270 to
360 K or to within approximately 10 K of the critical temperature
of the pure component with the lower critical temperature. A total
of 196 bubble point pressures are reported with combined expanded
uncertainties (k = 2) ranging from 0.1 to 0.6%. The
measured data are graphically compared to available literature data.
