The college of Science - Mathematics Dept. discussed a master's thesis entitled (Study Approximate Analytical  Solution   for Jeffery Hamel Flow  Problems by Using  Perturbation Iteration Algorithm ) by graduate student Ali G.A. The aim of the thesis is to study and solve the two-dimensional  Jeffery Hamel  flow  of an incompressible non-Newtonian fluid  problems in  a divergent-convergent  channels.
