The College of Science, Department of Mathematics, discussed a master's thesis entitled "Improving Analytical Solutions for Incompressible Fluid Flow Problems Using the Optimal Perturbation Iteration Algorithm" by postgraduate student Batool Abdulhakim Bada'. The thesis aims to study incompressible fluid flow problems, which generally represent physical phenomena. These problems are presented in two coordinate systems: Cartesian coordinates and cylindrical coordinates, which include the principles of conservation of continuity, momentum, and energy.
