shock tube [′shäk ‚tüb] (fluid mechanics) A long tube divided into two parts by a diaphragm; the volume on one side of the diaphragm constitutes the compression chamber, the other side is the expansion chamber; a high pressure is developed by suitable means in the compression chamber, and the diaphragm ruptured; the shock wave produced in the expansion chamber can be used for the calibration of air blast gages, or the chamber can be instrumented for the study of the characteristics of the shock wave.

California Institute of Technology, for example, uses TotalView on 128 processors of an IBM Power 5 machine running AIX -- for a shock tube simulation that provides insight into Richtmyer-Meshkov (shock-driven) instabilities and turbulent mixing physics. An 8-billion zone long-time simulation, emulating a shock tube experiment at Caltech, executed for 27,000 time-steps, represented over 300 quadrillion arithmetic operations. This will base-load ODA's shock tube plant located in Rhode Island. |
