This study presents a similarity analysis of the two-dimensional steady flow and heat transfer of a pseudoplastic visco-inelastic non-Newtonian Prandtl fluid over a stretching permeable surface. By employing a one-parameter scaling group transformation, the governing system of partial differential equations is reduced to a set of nonlinear ordinary differential equations. The scaling symmetry is systematically derived using group-theoretic methods to identify invariant solutions and corresponding similarity variables. The resulting boundary value problem is solved MATLAB ode solver. Effects of flow parameters on the velocity and temperature profiles are examined. Also, this study investigates the influence of suction/injection and the Prandtl number on velocity and temperature profiles in a boundary layer flow.
