DOUBLE STRATFIED FLOW OF NANOFLUID SUBJECT TO TEMPERATURE BASED THERMAL CONDUCTIVITY AND HEAT SOURCE

ABSTRACT
Stratified hydromagnetic flow of nanomaterial in the zone of stagnation point is addressed. An exponential base space dependent heat source, temperature dependent thermal conductivity and viscous dissipation are accounted. In addition, first order chemical reaction is present. The obtained non-linear system is computed by employing homotopic procedure. Convergent solutions are obtained. Plots and tabulated values are arranged for interpretation of sundry variables. Clearly temperature and concentration distributions are decayed in presence of stratification. Moreover skin friction and temperature are reduced via wall thickness parameter.
