The present paper is concerned to study the influence of second-order slip, mixed convection, viscous and Joule dissipations, thermophoretic and Brownian diffusions on steady stagnation point nanofluid flow over a stretching sheet embedded in a porous medium with passive control of nanoparticles. Graphs for velocity, temperature and concentration of present nanofluid flow model, obtained by using spectral relaxation method, are discussed in detail for various parameters. Apart from it, present results are verified by previously available results as well as regression analysis is performed for the local Nusselt number for making this model more effective in industries and engineering. From the statistical analysis of local Nusselt number, it is suggested that small variation in thermophoretic parameter leads to large perturbation in local Nusselt number in comparison to Brownian motion parameter, and the presence of Eckert number leads to strengthen Brownian and thermophoretic diffusions.

The present study analyzes the heat energy transfer in nano fluids flow through the porous stretching surface. Cattanneo-Christov heat flux model is employed to study the heat energy transfer. Darcy law is used to discuss the flow characteristics over the different types of permeable sheets with suction and injection. Nanofluids is considered as water based single-walled carbon nanotubes (SWNTs) and multi-walled carbon nanotubes (MWNTs) nanofluids. A comparative study for SWCNT and MWCNT is also made. Governing equations are transformed into set of ordinary differential equations using similarity transformations. The computational results are obtained by using Runge-Kutta fourth order method along with shooting technique. Numerical and graphical results are presented to discuss the effects of various physical parameters on velocity profile, temperature profile, Nusselt number, Sherwood number and skin friction coefficient for different type of nanoparticles for suction and injection cases. Stream lines and isotherms are also plotted for three different cases viz. permeable sheet with suction, impermeable sheet and permeable sheet with injection. A comparative analysis with existing results is tabulated which validate that the numerical results of present study have good correlation with existing results. The outcomes of the results show that skin friction coefficient is more for SWCNT in caparison of MWCNT and the boundary layer thickness is maximum for permeable stretching sheet with suction parameter.2010 Mathematics Subject Classification. 76Mxx.
