|Abstract: ||Two preliminary designs of a hydroacoustic gravity flow facility have
been developed for a Ship Silencing Laboratory, DTNSRDC, by Dr. George F.
Wis1icenus. It was desired to attain a test section velocity of 60 fps for
a 90 sec time period. As the facility will be used for acoustic measurements,
cavitation-free flow is a necessity. After a test run has been
completed, the water is returned by a pump in a separate line back to the
head tank. To ma~imize usage of the facility, the recycling time between
runs should be kept short.
As part of the overall development program, the Laboratory has been
asked to carry out some preliminary calculations on the proposed designs to
further establish feasibility and to independently evaluate the designs.
The calculations included an estimate of head loss in the system and an
elementary transient analysis. An alternate configuration also has been
suggested for consideration.|
