The College of Education for Pure Sciences at the University of Basrah organized a scientific lecture on an approximate analytical method for solving differential equations
The lecture presented by the student (Yasser Ahmed Abdel Amir) included an approximate analytical method for solving differential equations. In this episode, an analytical technique was proposed to solve the two-dimensional viscous flow model between slow expansion or contraction walls with weak permeability. The idea of ​​combining the Fourier transform and the homotopy perturbation method to produce a new technique was successful. The tables and graphs of the results of the new analytical approximate solutions show the importance, usefulness and necessity of using the new method. The results showed the accuracy and efficiency of the new method compared to the previous methods that were used to find approximate analytical solutions to the current problem.
