, 1962 The tests performed on a full-scale prototype of the closure designed for the Pathfinder reactor vessel are described. This head was bolted to another head designed to simulate the reactor vessel. The design pressure of the facility is 700 psig at 500 deg F. Strain gages and brittle coatings were used to determine the stresses in the closure.

Validation of a Surge Model by Full Scale Testing [PDF]
Volume 8: Turbomachinery, Parts A, B, and C, 2012 Surge of turbo compressors can cause large almost step like changes in flow and pressure, which can potentially damage the compressor and any equipment that is in direct connection with the compressor. In spite of an anti-surge controller (ASC), at extreme events surge cycles may occur. In order to design the compressor and attached equipment such that
