Abstract

Present investigation represent the study of Cattaneo-Christov heat flux model on boundary layer flow of hyperbolic tangent fluid which is generalized non-Newtonian fluid model over a continuously moving porous surface with a parallel free stream velocity. Mathematical formulation is completed in the presence of Magneto-hydrodynamics (MHD). Suitable relations transform the partial differential equations into the ordinary differential equations. Nonlinear flow analysis is computed and velocity and temperature profiles are obtained by shooting algorithm. Graphs are plotted to analyze the behavior of various involved physical parameters. Furthermore both type of flows Sakaidis ( λ = 1) and Blasius flow (0 ≤ λ <1) are discussed significantly. Special emphasis has been given to flow patterns for both types of flows, presented through stream functions contour and 3D plots. Key finding includes: Boundary layer thickness is an increasing function of power law index and Suction parameter for the case of Blasius flow, opposite to Sakaidis flow and dwindle of thermal boundary layer is witness for rising values of γ Pr, and S , while augmented boundary layer is observed for increasing values of n,M, and fluid parameter.
