“…This is accomplished by measuring the shock-front velocity Vs and using Equation 3. Numerous optical (18), piezo-electric (19), temperature (20), and electrical discharge (21) transducers have been described for this purpose.…”

“…The shock tube as an excitation source for spectrochemical analysis is capable of providing a region of uniform elevated temperature in which the temperature is accurately known and can be reproducibly controlled. This temperature can be varied from a few hundred degrees K to nearly 20,000 °K. The region of elevated temperature can be utilized both for vaporization of a sample and thermal excitation to excited electronic states.…”

natural water. Experiments with the Gota river water have shown that 25 ml of cyclohexane was lost by dissolution and 25 ml as droplets when extracting 200 1. of water. Knowing this, the results can be compensated for solvent losses. ACKNOWLEDGMENTThe authors wish to thank David Dyrssen for valuable discussions. We are also indebted to Soren Jensen for the provision of the polychlorinated biphenyls and to Birgitta Jarmark for technical assistance in the PCB analysis.

“…La méthode des sondes à film métallique mince consiste à ramener la mesure du flux à la détermination de la température superficielle du corps soumis à ce flux : cette mesure s'opère en suivant l'évolution dans le temps de la résistance d'une couche métallique mince déposée à la surface du corps considéré comme bon isolant thermique. Cette méthode utilisée depuis 1955 [1], [2], [3] pour la mesure de flux importants sur des maquettes placées dans l'écoulement d'une soufflerie à choc a été adaptée ici à la détermination de flux beaucoup plus faibles tels que ceux développés à la paroi d'un tube à choc fonctionnant à des nombres de à la décharge d'un condensateur de forte valeur pendant un temps bien déterminé de -0,1 à 10 millisecondesgrâce à des interrupteurs électroniques (thyratrons) : le flux constant et connu ainsi créé dans la sonde produit une tension de déséquilibre parabolique du pont 0394V(t) (relation (4) (fig. 3) qui permet de tracer la droite dV = 1(B,It-) fig.…”

2014 On décrit deux méthodes de mesure de flux de chaleur instationnaires au tube à choc particulièrement adaptées à la détermination de flux de l'ordre de quelques watts par centimètre carré. La première est l'application de la méthode classique des sondes à film métallique mince ; la seconde est basée sur la variation du signal de luminescence d'un sulfure cristallin en fonction de la température.Abstract. 2014 Two methods are reported for the measurement in a shock tube, of heat transfer rates of a few watts per square centimeter. The first is the application of the classical method of thin film gauges, the second is based on the principle of the luminescent response variation of a crystalline sulphide as a function of temperature.

A qualitative survey of one‐dimensional shock‐tube theory is presented first. The concepts discussed include: 1. the contact surface, 2. the incident and reflected shock wave, 3. the rarefaction wave, 4. interactions between shock and rarefaction waves, and 5. temperature and pressure versus time histories in shock‐tube experiments.Finally, a brief survey of measurement techniques suitable for determining the state of the gas behind incident and reflected shocks is presented. Techniques are discussed for measuring: 1. pressure, 2. density, 3. ionization and conductivity, 4. temperature, 5. light absorption and emission, 6. spectroscopic, 7. and light reflection.
