摘要: Abstract In this paper, the steady creeping flow equations of a second grade fluid in cartesian coordinates are considered; involve small parameter related to dimensionless non-Newtonian coefficient. According recently introduced approach, first order approximate Lie symmetries computed, some classes approximately invariant solutions explicitly determined, and boundary value problem is analyzed. The main aim paper methodological, considered mechanical model used test reliability procedure physically important application.
