Heat-transfer and operating characteristics of aluminum forced-convection and stainless-steel natural-convection water-cooled single-stage turbines

Description: Report presenting testing of two water-cooled turbines, one of aluminum alloy using forced-convection cooling and one of stainless steel using natural-convection cooling, to obtain heat-transfer and general operating data like blade temperatures, coolant-flow rates, and coolant pumping losses. Results regarding outside and inside heat-transfer results, coolant pumping power, general operating results, and practical considerations for both are provided.

A Design Study of Leading-Edge Inlets for Unswept Wings

Description: Note presenting a practical method, employing a lofting technique, for determining the profile coordinates of an air inlet for the leading edge of an airfoil from formulas which are dependent only on the airfoil coordinates and on the height of the opening. It was found that the base-profile concept of thin-airfoil theory could be applied to a ducted airfoil with satisfactory results. Results regarding design inlets, modified inlets, and end-closure shape are provided.

Solvent extraction of solutions containing rare earths. Preparation of thorium compounds from monazite by sulfuric acid decomposition and solvent extraction

Description: An investigation was made of the feasibility of producing pure Th compounds from monazite sand by a process involving the digestion of the sand with H/sub 2/SO/sub 4/ and separation of Th from the rare earths by solvent extraction. Direct extraction was not practicable. Precipitation of the sulfate from the system with lime and HNO/sub 3/ was tried and found to be partially successful but impracticable because of the large losses of Th by occlusion in the precipitate. A successful method for pr… more

The Distribution of Trace Uranium (VI) in Nitric Acid--TTA--Organic Solvent Mixtures

Description: Three constants can be used to calculate the distribution coefficient of uranium (VI) with an accuracy of 15% in pentaether-nitric acid mixtures containing up to 1.42M total nitric acid and 0.6M TTA and in cyclohexanone-nitric acid mixtures containing up to 1.0M total nitric acid and 0.5M TTA.
