Sound Propagation Into the Shadow Zone in a Temperature-Stratified Atmosphere Above a Plane Boundary

Description: Note presenting an investigation of the sound field about a point source over a plane boundary in the presence of a vertical temperature gradient, which represents one phase of a general program of research in atmospheric acoustics. In this report, geometrical ray acoustics is employed to derive the ray paths and intensity distribution about a source located in a uniformly stratified medium. Results indicate that the existence of a temperature gradient, which leads only to a simple refraction o… more

Measurements of thermal distortion of the submarine intermediate reactor "Mark A" moderator tube

Description: Report presenting a moderator tube of the Submarine Intermediate Reactor (SIR) ("Mark A") subjected to temperature gradients considered to be representative of those occurring in the reactor during operation. The distortion of the tube was measured under two conditions: with the ends of the tube retained in the same manner at the reactor and with the ends of the tube simply supported.
