The College of Education for Pure Sciences in the Department of Mathematics at the University of Basrah discussed a PhD thesis on (techniques and the study of fluid flow problems)
The thesis presented by the researcher (Taqiyyah Ahmed Jawad) included proposing new techniques to find approximate analytical solutions for different types of nonlinear fluid flow equations.
The first new method is based on the combination of Yang transformation and symmetric perturbation methods. The second innovative method is based on integrating the methods of Akbari Ganji and symmetric perturbation. These two methods have been used to address issues related to two-dimensional viscous fluid flow, transient normal convection, non-Newtonian viscoelastic fluid flow, and blood flow issues. The results obtained from the use of these two methods show that the new methods are effective and powerful in treating various flow issues, as well as they have high accuracy and good convergence compared to other methods.
