Flow and heat transfer in a power-law fluid over a nonisothermal stretching sheet

摘要: A boundary layer analysis has been presented for the problem of flow and heat transfer from a power-law fluid to continuous stretching sheet with variable wall temperature. similarity transformation is applied reduce Navier-Stokes energy equations, resulting system nonlinear ordinary differential equations solved using expansion Chebyshev polynomials. Parametric studies are performed investigate effects non-Newtonian index, generalized Prandtl number, surface temperature mass rate. The friction factor rate results exhibit strong dependence on parameters.
