| Popis: | This study intends to elaborate heat and mass transportation characteristics in unsteady flow of non-Newtonian fluid caused by oscillatory surface. The rheological behavior of non-Newtonian fluid is addressed by using Maxwell model. Further, heat transportation is characterized through consideration of Cattaneo–Christov theory of heat diffusion. Secondly, the generalized Fick’s law is implemented for investigation of mass transfer. The independent variables in the governing expressions are decreased with suitable transformations. The homotopic procedure is adopted for the solutions of well-defined problem. The validity of obtained solution is verified in limiting case. The graphical explanations for both linear and oscillatory stretching surface are presented. The comparison of $$f^{{\prime \prime }} (0,\tau )$$ with proposed results for linear stretching surface is recovered. Furthermore, the numerical values of flow feature parameters on local Nusselt and local Sherwood numbers are also highlighted and expressed in tabular form. |
