A seminar entitled New Analytical Study of Non-Newtonian Jeffery Hamel Flow of Casson Fluid in Divergent and Convergent Channels by Perturbation Iteration Algorithm holds at the College of Science, Department of Mathematics. The presenter Ali G. demonstrates the most important objective is presenting the using of the perturbation iteration algorithm (PIA)  to solve the Jeffery Hamel flow problem of non-Newtonian fluid which is Casson fluid (JHFCF).
