Cattaneo-Christov intensity of magnetised upper-convected Maxwell nanofluid flow over an inclined stretching sheet: A generalised Fourier and Fick's perspective

The present study exemplifies the systematic analysis of the boundary layer Cattaneo-Christov model of heat and mass transport of the upper-convected Maxwell nanofluid passed by an inclined stretching surface in the presence of magnetic field. The pioneering step i.e. the upper-convected material derivative has been constructed to frame generalised Fourier's and Fick's phenomenon on behalf of the Cattaneo-Christov model. Governing non-linear PDEs are renovated to ODEs and then worked out via RK-4 procedure. Influences of flow factors inside flow regime, namely, fluid relaxation parameter delta(e), thermal relaxation parameter delta(e), nanoparticle concentration relaxation parameter are deliberated through tables and graphs to predict the double diffusive phenomenon truthfully. Our investigation authenticates that higher temperature distribution profile is noticed for delta(e)=0.0 i.e. so called Fourier's law as compared to Cattaneo-Christov heat flux model. Thus the significance of the current literature is to explore its unique endeavour towards the generalised version of conventional Fourier's law and Fick's law at nanostructure level.
