Lie group analysis for the effect of temperature-dependent fluid viscosity and thermophoresis particle deposition on free convective heat and mass transfer under variable stream conditions

This paper examines a steady two-dimensional flow of incompressible fluid over a vertical stretching sheet.The fluid viscosity is assumed to vary as a linear function of temperature.A scaling group of transformations is applied to the governing equations.The system remains invariant due to some relations among the transformation parameters.After finding three absolute invariants,a third-order ordinary differential equation corresponding to the momentum equation and two second-order ordinary differential equ...
