Abstract

The steady-state Eyring–Powell boundary layer fluid flow past a moving surface is examined, considering various parameter implications. These include the wall mass transfer parameter (0.5  C   2.0), the magnetic field parameter (5  Mn 20), the velocity ratio parameter (0.1  λ1  0.7), Eyring-Powell fluid parameters (0.5 K 2 & 0.1 E 0.4), as well as the first-order velocity slip (0.1 γ 1.1) and second-order velocity slip (0.1 δ  0.4). By employing appropriate similarity transformations, the PDEs are reduced to a set of non-linear ODEs, which are subsequently solved using the bvp4c numerical technique and, an implication of key factors on shear stress as well as velocity, is illustrated and interpreted through picturesque representation. An important novelty of the present study lies in the investigation of steady-state Eyring-Powell fluid model boundary layer flow past a moving surface, as well as a comprehensive examination of governing parameters. Outcomes are provided for distinct governing parameter  values, compared with previously published findings. As a result, the obtained outcomes will only, not offer valuable insights for technical purposes but also serve to counterpart prior research. Flow rates and velocity gradients  near the boundary wall increase approximately 1.7% to 2.4% when slip conditions are introduced, including second-order slip. Eyring-Powell's primary velocity is suppressed by around 12% to 15% by the Lorentz damping induced by the magnetic parameter. The velocity distribution within the boundary layer is significantly enhanced when increasing the Eyring–Powell fluid model parameter and the second-order velocity slip parameter. A higher Eyring-Powell parameter number and a higher second-order velocity slip number also show an increase in the skin friction coefficient.
