基于TDMA算法的ADI算法，同样是流体流动与相变传热的数值模拟课程的课堂小作业，采用有线差分法，计算二维平板的流体稳态流动时的热扩散稳态。-ADI algorithm for TDMA-based algorithm, the same phase change heat transfer and fluid flow numerical simulation of a small classroom course work, the use of wired-difference method to calculate the flat two-dimensional steady-state flow of fluid when the steady-state thermal diffusion.
