内容記述 | The present paper concerns with the CO_2-GDL experiment by means of a snap-action type of shock tubes, which are deviced so as to be driven by free piston quick valve instead of diaphgram breaking. A part of experiments are conducted by the tube (Type II) with an improved driven mechanism. The CO_2-N_2-He mixture is used as a test gas. The stagnation condition covers from 1.5 to 8.5 kg/cm^2 in pressure, and from 1,100 to 3,000°K in temperature. The laser power is measured using the Hg-Cd-Te infrared radiation detector calibrated by CW CO_2 laser. Four different types of two-dimensional nozzles and a multiple conical nozzle are employed in order to examine the effect of nozzle configuration on the laser power extracted. First, the optimum operation condition regarding laser power is examined for various stagnation pressures and temperatures. It is found that the power density depends strongly on the stagnation temperature while weakly on the stagnation pressure. Secondly, the power distributions along as well as normal to the flow direction are measured. The total power is roughly close to the one predicted by an analysis of quasi one-dimensional steady flow, but the feature of the power distribution is quite different from the one by the analysis. Moreover, the record of the power with time indicates highly oscillatory mode with many sharp spikes. The theoretical explanation will remain in future study. It should be remarked that the total power as well as the power distribution are not appreciably affected by the nozzle configuration for the throat-exit area ratio fixed so far as the present experiment is concerned. | |||||
