Linear And Vortex Flow Heat Transfer Coefficients, Edward Robert Schmidt Jr. Jan 1959

Linear And Vortex Flow Heat Transfer Coefficients, Edward Robert Schmidt Jr.

Masters Theses

"In order to make possible better, more efficient equipment, a higher and higher rate of heat transfer has been the goal of engineers for many years. The need for heat transfer rates never thought of 25 years ago has been brought about by the advent of modern high-performance devices such as nuclear reactors and rocket motors. "A heat release of about 40,000 Btu/hr.cu.ft. is considered good practice in a modern boiler, but in a rocket or a nuclear reactor it may be 1,000,000,000 Btu/hr.cu.ft." This heat must be removed by transfer to a coolant or converted into work or the …


A Study Of The Adsorption Of Radioactive Zirconium, Niobium, Cesium, And Barium On Alumina, Silica Gels And Clays, Dale Wesley Harris Jan 1959

A Study Of The Adsorption Of Radioactive Zirconium, Niobium, Cesium, And Barium On Alumina, Silica Gels And Clays, Dale Wesley Harris

Masters Theses

"The purpose of this investigation was: (1) search the literature and review various methods investigated for the safe storage of radioactive waste products, (2) study the possible methods for the recovery, of useful radioactive isotopes by selective adsorption, (3) perform laboratory tests to determine the capacity of various adsorbents for radioactive isotopes, (4) evaluate the data and correlate it with the findings reported in the literature, (5) make recommendations of the feasibility of using these adsorbents for removal or storage of the radioactive products, and (6) make recommendations for further investigations. The adsorption of radioactive zirconium, niobium, cesium and barium …
