Rate-Controlled Separations
Separations have always been very important in chemical engineering This importance has escalated with the emergence of new industries in biotechnology and high performance materials. Separations will continue to remain important in bulk chemical manufacturing, petroleumprocessing, and the other standard areas of interest in chemical engineering.
This book covers separation processes which require a rate analysis for complete understanding. This includes most of the newer separation methods. Problem solving is emphasized throughout. A level of mathematical analysis is required, and an understanding of mass transfer is assumed.
The book starts with crystallization, which is essentially equilibrium-based. The author then considers sorption separations, which can be (but seldom are) operated as equilibrium-staged systems, and membrane separations, which are inherently rate processes. Finally, there is a progress report on selection and sequencing of separations.
The book is directed at senior undergraduate and graduate students of chemical engineering..

Experimental Investigation of Vortex Shedding in Flow Over Second- Generation, Controlled-Diffusion, Compressor Blades in Cascade
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A697104. The abstract provided by the Pentagon follows: An investigation of vortex shedding downstream of a cascade of second-generation, controlled-diffusion, compressor stator blades, at off-design inlet-flow angles of 31, 33 and 35 degrees and Reynolds numbers, based on chord length, of 280,000, 380,000 and 640,000 is reported. The objective of the study was to characterize the flow and shedding through various complementary methods. Blade surface pressure measurements were taken from a fully instrumented blade, and distributions of pressure coefficients were determined. Five-hole probe wake surveys were performed at midspan, and the total pressure loss coefficients and axial velocity ratios were calculated. Upstream inlet-flow angle was set, and further characterized through two-component laser- Doppler velocimetry (LDV). Hot-wire anemometry measurements were performed at midspan, in the wake, and the reduced data were compared with two-component LDV surveys of the same regions. Plots of hot-wire vs. LDV turbulence data are reported in addition to power spectra documenting the shedding events. Vortex shedding was determined to be a leading edge phenomenon as periodic shedding was only detected on the pressure side of the wake. The frequency and magnitude of shedding were found to be independent of incidence angle, and to increase with Reynolds number at constant incidence angle. The Strouhal number, based on leading edge diameter, was found to be in the range of 0.23-0.26, which is comparable to that of vortex shedding behind a circular cylinder in the Reynolds number range tested..
