The main focus of the first three year period of this research program was to set up our liquid helium flow facility and begin experiments on the flow of liquid helium within this system. The first task of our experimental program involved the set up and check out of the liquid helium flow facility (LHFF). This facility is the centerpost of our fluid dynamics experiments. The LHFF is designed to allow a variety of experiments which test important helium fluid dynamics behavior on a scale close to that involved in large scale applications. To achieve this goal, we chose a horizontal dewar configuration with a cold bore access on either end. A nominal length of five meters was selected with a sufficiently large inner diameter to allow insertion of various tubing configurations, flow metering devices and heat exchangers. Further, to minimize consumption of liquid helium, the dewar design includes two actively cooled shields; one cooled by LN/sub 2/ to 77 K and one at 4.5 K maintained by a closed cycle helium refrigerator. Helium flow is to be provided by a cold centrifugal pump. 4 refs., 2 figs.
