Numerical study of boundary layer injection as a scale control method (open access)

Numerical study of boundary layer injection as a scale control method

A boundary layer injection method of controlling scale-buildup in geothermal two-phase flow nozzles is studied. The object of this study is to set an upper limit on the ratio of the injected mass flow rate to the free stream mass flow rate that is necessary to isolate the scale carrying free stream flow from the nozzle wall. In order to develop a numerical model of the boundary layer flow, assumptions are made which reduce the results to order of magnitude approximations. Two configurations of nozzles with various injection flow rates are tried. It is found by numerical experiment that a nozzle with injection through a 1 mm thick ring near the inlet, is more efficient at isolating the free stream than a porous nozzle. A mass flow rate ratio of 0.173% was necessary to achieve this effect. It may be concluded that an upper limit on the mass flow rate ratio is about 2.0% with injection through a ring near the inlet, and that boundary layer injection is a reasonable method of controlling scale-buildup. A glossary of variables, program documentation and listings are presented for programs GMD15SR8, TRACK11, and TRACK12.

Studies in Development Immunogenetics. Annual Progress Report (open access)

Studies in Development Immunogenetics. Annual Progress Report

This contract provides the research support for a group concerned with a relatively large range of problems. The integrating thread that runs through it is that of an interest in development and its genetic regulation, mainly in complex organisms and with an emphasis on the immune system as a model for developmental analysis and as a tool for following the development of other systems, especially the brain. It includes studies of biochemical genetics, primarily from a developmental viewpoint and with particular regard to defense mechanisms, and cellular aspects of the immune system. It extends into the area of cancer immunology and cell specificities as related to tumor systems, primarily from an immunogenetic viewpoint and with particular reference to leukemias in the mouse, and to disruptions of genetic control mechanisms in tumor development, especially as approached through the reappearance of fetal antigens associated with tumor development.

[Alumni Awards Luncheon, April 26, 1975]

Photograph from the Alumni Awards Luncheon, Saturday April 26, 1975 at the Denton Country Club. From left: Tom Harpool (North Texas State Teachers College 1939), President of the North Texas State University Alumni Association; Joe Greene (North Texas State University 1966-1969); Dr. Chester A. Newland (North Texas State College 1954); and Larry Jobe (North Texas State College 1961). At the luncheon, Greene, Newland, and Jobe were each awarded the Alumni Association Distinguished Alumni Citation. At the time this photograph was taken, former North Texas football player Greene was a left tackle for the Pittsburgh Steelers, and had just won AFC Champ, been part of the winning team in Superbowl IX, been in his 5th consecutive Pro Bowl, and had been named NFL Defensive Player of the Year for the second time. Dr. Newland, former director of the LBJ Library, was Executive Director of the Federal Executive Institute. Mr. Jobe had been Assistant for Administration, U.S. Department of Commerce, and was a managing partner of Alexander Grand & Co.
