The behavior of rotary face seals is being studied by means of an instrumented transparent model which allows direct observation of the fluid in the seal gap during operation. The seal apparatus was designed, constructed, and commissioned. Initial operation has not disclosed any serious problems, although a revised water-circulating system which substitutes a double loop for the former single-loop system, is being installed. Instrumentation for determining the dynamic-seal gap width was evaluated and seems satisfactory for the purpose intended. The early experiments will be directed at studying the film-rupture phenomenon in the seal interface. A packed-gland seal facility was designed and constructed. The facility will be capable of handling both conventional and inverted packingseal corfigurations. Instrumentation will include means for measurement of packing temperature and frictional torque and optical systems for direct observation of the packing rubbing interface. (auth)
