摘要
应用 Tikhonov正则化方法和有限差分法 ,研究了一维非恒定紊动扩散初始条件反问题 ,给出了一种数值求解方法。数值模拟结果表明 ,该方法是可行的 。
In this paper, Tikhonov’s regularization Scheme and finite difference are used to research initial condition inverse problem of one dimensional unstable turbulent diffusion, and also the method of numerical solution is offered.The results of numerical simulation show that the method is viable and has a higher accuracy.
