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.
