The paper presents semi-analytical/semi-numerical methods for the solution of steady
viscous flow between two porous disks due to stretching motion in the presence of
suction/injection with mass transpiration (λ). The governing boundary layer equations for the
flow problem are reduced to a single nonlinear ordinary differential equation (NODE) by
using similarity transformation. The resulting NODE is solved by computer extended series
solution (CESS) and homotopy analysis method (HAM) with relevant boundary conditions …

In this work, an exact solution to the steady-state Navier–Stokes (NS) equations is presented
for viscous flows between two stretchable disks with mass transpiration effects. The
governing momentum equations were converted into an ordinary differential equation by a
similarity transformation technique. The similarity equation was solved numerically and the
effects of Reynolds number and the mass transpiration parameter were investigated. At very
low Reynolds numbers (ie, R→ 0), a creeping flow was observed with a parabolic radial …
