On non-Fourier flux in nonlinear stretching flow of hyperbolic tangent material

The present study explores the features of hyperbolic tangent material due to a nonlinear stretched sheet with variable sheet thickness. Non-Fourier flux theory is implemented for the development of energy expression. Such consideration accounts for the contribution by thermal relaxation. The resulting nonlinear differential system has been determined for the convergent series expressions of velocity and temperature. The solutions are demonstrated and analyzed through plots. Presented results indicate that velocity decays via larger material power law index and Weissenberg number. Temperature is the decreasing function of Prandtl number and thermal relaxation time.
