Abstract
The communication here addresses the impact of heterogeneous-homogeneous reactions in boundary layer flow of nanofluid saturating porous medium. The stretching cylinder caused the flow in presence of melting heat transfer. Analysis for single-wall carbon nanotubes (SWNTs) and multi-wall carbon nanotubes (MWNTs) is explored. Water is taken as the base fluid. Auto catalyst and reactant both have same diffusion coefficient. Boundary layer problems are computed for the velocity, temperature and concentration. Resulting differential systems are evaluated for the convergent series solutions. Outcomes for the velocity fâ²(η), temperature θ(η) and concentration Ï(η) are examined. The skin friction coefficient fâ³(0) and Nusselt number θâ²(0) are also explored. It is found that temperature θ(η) and velocity fâ²(η) have reverse effects for melting parameter M. Concentration distribution Ï(η) is decreasing function of homogeneous reaction parameter K while opposite influence of heterogeneous reaction appears. Maximum heat transfer and minimum thermal resistance are noticed for MWCNTs than SWNTs.
