| Abstract: | The method of Orthogonal Collocation on Finite Elements (OCFE) is successfully applied in solving the set of stiff ODEs representing the absorption with rapid second-order chemical reactions taking place in the liquid film. A proper transformation of original equations is performed to make the application of OC method possible. Compared with OC method , OCFE method has more advantages in dealing with stiff equations and shows greater flexibility, higher accuracy and efficiency. |
