尽管激光诊断技术已经有了很大的进步，可以获得速度场的瞬时2D火焰图像，但仍然很难从实验上获得标量通量或反应速率等数据。了解湍流燃烧中的三维火焰结构也是非常必要的。化学非反应湍流是复杂的，化学反应使问题更加复杂。由于计算成本的实际限制，传统的数值方法在高雷诺数下进行详细的化学反应的三维数值模拟是非常昂贵的。在本研究中，我们使用了格子Boltzmann方法(LBM)来模拟燃烧场。对于这类流动的数值模拟，LBM是一种有效的选择。为了验证LBM的有效性，对简单流动几何结构的火焰进行了数值模拟，得到了层流燃烧速度。二维和三维模拟均已完成。为了验证LBM对有涡非定常火焰的模拟能力，还对一个喷流火焰进行了模拟。该方案对逆流火焰进行了详细的化学模拟。
Even though laser diagnostics have significantly improved and can obtain an instantaneous 2D flame image of the velocity field, it is still difficult to obtain data such as scalar flux or reaction rates experimentally. It is also essential to understand 3D flame structures in turbulent combustion. Chemically non-reacting turbulent flows are complex and chemical reactions make the problem more complicated. Due to practical limitations of computational costs, conventional numerical methods are very expensive for carrying out 3D numerical simulations at high Reynolds numbers with detailed chemical reactions. In this study, we have used the lattice Boltzmann method (LBM) to simulate a combustion field. The LBM is an efficient alternative for the numerical simulation of this type of flow. To confirm the validity of the LBM, a flame in simple flow geometry is simulated and the laminar burning velocity is obtained. Both 2D and 3D simulations have been completed. A jet flame has been also simulated to demonstrate the LBM capability of simulating unsteady flames with vortices. The scheme with detailed chemistry has been tested for simulation of a counter-flow flame.
