<p>To achieve the global goal of decarbonization, use of hydrogen in place of fossil fuels is expected to increase worldwide. In this study, to establish a hydrogen combustion technology of boilers for a safe, low NOx and low cost, a combustion test of a hydrogen burner was carried out in a large model furnace, and it was confirmed that supplying hydrogen fuel to the burner at a high pressure that has never been used before reduces NOx. In addition, the mechanism of NOx reduction by increasing the supply pressure was newly clarified by the numerical analysis (LES) of hydrogen combustion field. The high-pressure hydrogen supply was also effective for the cost reduction, and the prospect of the application to the actual use of the hydrogen burner was obtained.</p>

It is well known that high-pressure shock waves are generated during the collapse of bubbles, on which an underwater shock wave acts. In this study, the effects of bubble gas composition on the generation of shock waves in a bubble collapse were investigated experimentally. The explosive bubbles were composed of a stoichiometric ethylene-oxygen mixture and a stoichiometric hydrogen-oxygen mixture, whereas the gas compositions of the chemically inert bubbles were air and helium. The initial volume-equivalent radius of the bubble varied from 1.0 to 3.9 mm. The nondimensional maximum pressure of the bubble-generated shock wave was inversely proportional to the non-dimensional distance from the bubble for both explosive and chemically inert bubbles. The proportionality factor for the explosive bubbles was higher than that for the chemically inert bubbles. However, the proportionality factor for the hydrogen-oxygen bubble was slightly lower than that for the ethylene-oxygen bubble. This trend occurred because the high reactivity of the hydrogen-oxygen mixture caused an earlier explosion in the shrinkage stage. Regardless of the bubble composition of the gas, the conversion ratio from the bubble energy to the shock energy increased with decreasing momentum acquired by the water around the bubble.

<p>Soot formation process has been extensively studied over the last decade and is still a crucial issue for reduction in exhaust emission of internal combustion engines. In this article, researches on soot formation using shock tubes are introduced in terms of measurement techniques of soot particles such as laser scattering/extinction method and laser-induced incandescence. Furthermore, ambient temperature rise during soot formation process is mentioned, with reference to measurement of soot particle temperature. Besides research progress in the soot formation, an operation principle of a standard shock tube is described together with several cautions when using a shock tube as a chemical reactor to realize homogeneous high temperature fields.</p><p>Soot formation process has been extensively studied over the last decade and is still a crucial issue for reduction in exhaust emission of internal combustion engines.
