摘要
通过对大加速度场中层流燃烧室流场的数值计算,建立了大加速度场中二维层流燃烧的数学模型,对控制方程组进行离散,采用SIMPLE算法和交错网格设计并调试程序,对丙烷和空气在大加速度场中的预混燃烧过程进行了数值模拟。计算结果表明,沿燃烧室轴线方向的大加速度场确实会对预混火焰的速度场和温度场等产生明显影响。
The simulation of laminar flow combustion process in the large acceleration field was proposed. The math model of two-dimensional laminar flow in large acceleration field was set up, in which dispersed the equation of combustion system, designed and debugged the program to simulate the combustion process in large acceleration by SIMPLE algorithm, and staggered grid system. The numerical simulation on prepmixed combustion process of propane and air was carred out. The results of calculation indicated that the uniformity large acceleration field of the combustion chamber axes direction certainly affected the velocity field and the temperature field of the premixed flame.
