Abstract:
Pressure measurements at three different locations in the driver section of a shock tube reveal that the expansion wave generated by diaphragm rupture can be effectively viewed as a simple centered expansion wave whose origin is slightly shifted with respect to the origin of an ideal x-t diagram. The resulting centered expansion wave is used to study the condensation of water, heavy water, benzene, carbon tetrachloride and Freon 11, in an excess of the non-condensing carrier argon. Simultaneous pressure and light scattering measurements determine the onset of condensation. The isentropic flow within the expansion wave is found to be preserved up to the point of the detectable onset of condensation by tailoring the onset conditions to occur at the tail of the expansion wave, thus rendering a simple analysis of the experiments possible.
