摘要: Abstract The non-linear differential equation for the magnetohydrodynamic Poiseuille flow of Phan-Thein–Tanner (PTT) conducting fluid is derived. Using homotopy analysis method (HAM), series solution developed and its convergence discussed. Also, results are presented graphically effects non-dimensional parameters on field analyzed. obtained reveal many interesting behaviors that warrant further study equations related to non-Newtonian phenomena, especially shear-thinning phenomena. Shear thinning reduces wall shear stress.
