An Optimal Iteration Algorithm for Multi-parameters Inversion in Multi-components Solutes Transportation

Based on a mathematical model for multi-components solutes transportation in porous medium, an inverse problem of determining multi-parameters is put forward, and the inverse problem is transformed to a minimization problem. Furthermore, a modified optimal iteration algorithm is applied to determine the unknown model parameters and numerical simulations are performed. The computational inversion results show that the optimal iteration algorithm used in this paper is efficient at least to the inverse problem of multiparameters identification arising from a group of advection-dispersion equations.
