Conventional combined PSP/TSP sensors suffer from the photodegradation caused by interaction between PSP and TSP luminophores. In the proposed sensor, dot arrays of PSP and TSP were separately arranged for avoiding the interaction. The PSP and TSP dots were made of PtTFPP and CdSe/ZnS, respectively, so that the luminescences from each dot array could be separately detected by optical filters. We investigated fundamental properties of the dot array sensor: photostability, pressure sensitivity and temperature sensitivity. As a result, the photodegradation was not observed in the dot array sensor. It was also shown that PtTFPP dot array had the pressure sensitivity of 0.53%/kPa, and CdSe/ZnS dot array had the temperature sensitivity of -0.61%/K, which were almost the same sensitivities as conventional PSPs and TSPs. Therefore, the proposed sensor will be a preferable sensor for the simultaneous measurement of pressure and temperature.","PeriodicalId":331123,"journal":{"name":"Transactions of the Japan Society of Mechanical Engineers.

In the LIF method, an argon-ion laser is used as a light source to excite the iodine molecules seeded into the working gas. The iodine fluorescence, whose intensity is known to be a function of temperature, is detected by the photomultiplier. The pressure oscillation on the bottom wall of the cavity is also measured simultaneously with the fluorescence detection. The phase of fluorescence-intensity oscillation is corrected on the basis of the cavity-bottom pressure oscillation and the correction is performed at every fluorescence detection point. As a result, the temperature oscillations inside and outside the cavity are qualitatively visualized in two-dimensional sense. In the schlieren method, the light source is controlled so as to flash responding to a specific phase of the periodic pressure signal and the oscillatory motion of the shear layer developing along the cavity span is captured. By carefully observing both of the visualization results, the relation between the temperature oscillation and shear-layer motion is clarified.","PeriodicalId":331123,"journal":{"name":"Transactions of the Japan Society of Mechanical Engineers.

The extinction limits can be divided into two regions. One is a diffusion flame dominant extinction region (DF-DE) in which equivalence ratio of LPF side (φL) at extinction limit is decreasing linearly with increasing fuel concentration of DF side (χU). The other is a lean premixed flame dominant extinction region (LPF-DE) in which effect of χU on extinction φL is increasing with increasing χU. In these two regions, the flame structures and its φL dependence are different greatly. In the DF-DE, the temperature has symmetrical profile regardless of φL and the temperature peak is located near DF. Since DF has higher temperature than LPF, LPF is thermally supported than DF. Temperature gradients between two reaction zones are decreasing with increasing φL, while laminar burning velocity (SL) and burnt gas width (WB) are constant regardless of φL. On the other hand, in the LPF-DE, the temperature has asymmetrical profile and the temperature peak leans to the LPF side. That is, the temperature gradient of LPF side is very steep compared with the DF side. Since LPF has higher temperature than DF, DF is thermally supported than LPF. Temperature gradients between two reaction zones are constant regardless of φL, while SL and WB are increasing with increasing φL.","PeriodicalId":331123,"journal":{"name":"Transactions of the Japan Society of Mechanical Engineers.
