Experimental Studies on Attenuation of Pressure Waves Induced by Thermal Shocks

PDF Version Also Available for Download.

Description

High magnitude pressure waves are expected in the mercury-filled Spallation Neutron Source target system. An appropriate measure is needed to protect the target system from such high pressure waves. It has been known that inclusion of devices like scattering centers in the pressure field will attenuate pressure waves by scattering waves between scattering centers. A series of experiments have been conducted to test such a concept. After verifying the concept by performing simple scoping experiments, fives series of experiments were conducted with various configuration to measure changes in sound speed and pressure amplitude with inclusion of various scattering centers.

High magnitude pressure waves are expected in the mercury-filled Spallation Neutron Source target system. An appropriate measure is needed to protect the target system from such high pressure waves. It has been known that inclusion of devices like scattering centers in the pressure field will attenuate pressure waves by scattering waves between scattering centers. A series of experiments have been conducted to test such a concept. After verifying the concept by performing simple scoping experiments, fives series of experiments were conducted with various configuration to measure changes in sound speed and pressure amplitude with inclusion of various scattering centers. Results indicate that for the conditions of our test, no significant change in sound speed was observed; however, substantial attenuation of pressure waves was detected with scattering centers in mercury.
