The theoretical and experimental study on space-time three-dimensional structure of turbulent flame was done by using direct numerical simulation and laser measurements (LIF, PIV, et al.).1) Direct numerical simulationThe direct numerical simulations was carried out to verify combination method based on laminar famelet model in unsteady transitional jet flame, to elucidate the effects of concentration profile of premixed gas on flame structure of triple flame, and to examine the role of elementary reactions in flame structure and unsteady behavior of premixed flame stabilized by V-gutter holder.2) Laser measurementLaser measurement was carried out to elucidate the unsteady flow behavior around a V-gutter by PIV.3) Comparison of theoretical and experimental resultsThe obtained theoretical and experimental results were compared with each other.

采用直接数值模拟和激光测量（LIF、PIV等）方法，对湍流火焰的时空三维结构进行了理论和实验研究。1)直接数值模拟对基于层流火焰面模型的组合方法在非定常射流火焰中的应用进行了验证，研究了预混气体浓度分布对三重火焰火焰结构的影响，并研究了基元反应在V型槽稳定器预混火焰结构和非稳态行为中的作用。2）3）理论与实验结果的比较将理论结果与实验结果进行了比较。
