| 摘 要： | 为了求解二维非稳态对流扩散方程的参錾反问题，利用有限元方法给出其正问题的求解，将结果作为附加条件，结合混沌局部搜索算法的优点，提出了一种改进的混沌粒子群优化算法．数值模拟结果表明此方法所得到参数反演的数值解与真解误差很小，目标值达到10^-4，精度较高．

| Abstract: | In order to solve two-dimensional non-steady-state convection-diffusion equation of the parameters inverse problem, using the finite element method to give its positive question solution as additional conditions, and combining with the advantages of chaotic local search algorithm,an improved chaotic particle swarm optimization algorithm is proposed. The simulation result shows that the error between the numerical solution of parameter inversion and the true solution is very small, the target value is up to 10-4. The method has higher accuracy. |
