基于TDMA算法求解点燃时间的研究

摘要

为求解材料点燃时间，对能量控制方程和边界条件进行无量纲化、离散化再用TDMA进行求解，理论解与实验差别较大。对实验得到的点燃时间拟合求得吸收系数以及热损，再用TDMA进行求解可以得到点燃时间和实验值非常接近。%In order to calculate the ignition time,the energy equation and boundary condition are non-dimensionalized,dis-cretized and solved by TDMA.It turn out that there is a greater difference between the theoretical solution and experimental. Fitting the ignition time,the absorption coefficient and heat loss are count.Then the TDMA algorithm show that the result is very close to the experimental value.
