• The methods to investigate the soot formation are studied experimentally with a co-flow burner. In this study, the soot volume fraction, soot particle diameter and number density in a laminar diffusion flame are measured with LII(Laser Induced Incandescence)/LIS(Laser Induced Scattering)techniques. For the purpose of quantification, validation test is needed to be conducted before LII/LIS technique is applied to measure soot formation, and the development of algorithm is also required to analyze the raw data. In the present study, the extinction and scattering tests with a co-flow burner were performed to acquire calibration data. From this result, we decided the optimal laser beam intensity and obtained the LII signal from the diffusion flame. In addition, the algorithm for LII/LIS simultaneous measurement is developed and applied to this algorithm to measure the soot volume fraction in the diffusion flame.
