Heat Exchanger Design Charts (open access)

Heat Exchanger Design Charts

From introduction: "The ORNL-ANP liquid-to-liquid heat exchanger design and development effort has been based on an exceptionally high performance matrix of closely-spaced small diameter tubes that permits practically pure counter-flow operation. In the course of full-scale aircraft power plant design work a number of charts for this type of heat exchanger has been prepared. These charts were intended in part to show the effects of the various parameters in a readily understandable form, and in part to simplify and to reduce markedly the chore of making detailed design calculations. These charts have proved so helpful it seemed very worthwhile to assemble them into a report along with brief explanations and sample calculations."

Possible water flow rates at DR and H Piles (open access)

Possible water flow rates at DR and H Piles

Estimated water flow rates at H Pile for various postulated conditions are given. The conditions under which the data are valid are as follows: (1) the estimated accuracy of the tube flow rates is {+-}5%, and of pile flow rates {+-}7%; (2) the pile flow rates are based upon the present tube geometry, orifice zone pattern and total flow at H Pile; (3) the flow rates should be increased about 2% if film-free slugs and tubes are considered; and (4) flow rates for enlarged fittings are based upon fittings similar in shape to the present H Pile fittings. The maximum tube flow rates for the DR Pile would be about 2% greater than those given in the table for present tube fittings. For enlarged fittings, the rates for DR Pile tube would be the same as those given for H Pile tubes. The ultimate permissible flow will depend, in part, upon limitations on maximum cross-header pressure and maximum tube inlet pressure, and upon the instrumentation necessary to detect abnormal tube flow conditions.

Equipment description of proposed RDA-5 canning machine (open access)

Equipment description of proposed RDA-5 canning machine

The General Engineering Laboratory has submitted a cost estimate and a proposal covering the design, fabrication, construction, and testing of a uranium slug canning machine. This machine will cover requirements for mechanization of only the operations occurring within the aluminum-silicon canning bath. These operations are: Can and cap preheating, Can and cap wetting, Canning assembly, and Quenching. Stated briefly, the machine is required to insert a prepared uranium slug into an aluminum can and close the can opening with an aluminum cap. All assembly operations will be carried out beneath a molten bath of standard Hanford aluminum-silicon bonding alloy. The uranium slug is preheated and prewetted before being manually transferred to the slug assembly and quench machine. The process performed by the machine will be integrated with the manual slug preheating and wetting equipment so that proper preheating and wetting is attained before the slug is inserted into the machine. After assembly the completed canned slug will be transferred to the water quenching station, where the components are held firmly together until the molten aluminum-silicon has frozen, forming a homogeneously bonded assembly. This report provides a detailed description of the machine.

Measurements of Pressure Drop with No Heat Addition on Mockup Segments of the General Electric Air-Cooled Aircraft Reactor (open access)

Measurements of Pressure Drop with No Heat Addition on Mockup Segments of the General Electric Air-Cooled Aircraft Reactor

"An investigation was conducted at the NACA Lewis laboratory to obtain pressure-drop data for flow of air with no heat addition through mockups of two reactor segments of the proposed General Electric Company aircraft reactor. Pressure-drop data were obtained over a range of Reynolds numbers from 4000 to 80,000, air inlet Mach numbers from 0.02 to 0.40, inlet pressures up to about 40 inches of mercury absolute, and ambient air temperatures. factors, corrected for entrance, vena contracta, momentum, and exit losses, are considerably higher at the high Reynolds numbers than those reported for turbulent flow in smooth pipes" (p. 1).
