对层流三重火焰的结构进行了实验和数值研究。利用激光诱导荧光技术绘制了火焰中OH自由基的分布图。速度场的结构映射使用粒子成像测速仪。为了获得速度场和标量场的详细信息，对火焰进行了数值模拟。在模拟中，气体膨胀被考虑和完整的Navier-Stokes方程求解。与全球一步化学，或者，与详细的化学动力学机制得到的数值结果。实验结果与数值结果进行了比较。
The structure of a laminar triple flame is investigated both experimentally and numerically. The distribution of OH radicals in the flame is mapped using Laser Induced Fluorescence. The structure of the velocity field is mapped using Particle Imaging Velocimetry. To obtain detailed information on both the fields of velocity and scalars, the flame is numerically simulated. In the simulations, gas expansion is taken into account and the full Navier-Stokes equations are solved. Numerical results obtained with global one-step chemistry and, alternatively, with a detailed chemical kinetic mechanism are presented. The experimental findings are compared with the numerical results.
