Impacts of homogeneous-heterogeneous chemical reactions and inclined magnetic field on unsteady nanofluids flow

Abstract

An analytical investigation of time-dependent, laminar boundary layer nanofluid flow through a non-linear stretching sheet with inclined magnetic field is addressed. Flow analysis and formulation are given acounting homogeneous-heterogeneous reaction impacts. The governing flow equations with suggested boundary conditions are simplified through proper transformation. Series solutions convergence utilizing homotopy analysis method (HAM) are provided for velocity, temperature and concentrations. The significant physical quantities that affect the velocity, temperature and concentration curves are exhibited through graphical figures and tables. The results elucidates that the homogeneous reaction and heterogeneous reaction parameters produce a reduction in concentration distribution. Further, the inclination angle parameter of magnetic field gives an increment in temperature curves whereas reduces the concentration and velocity fields. Local Nusselt number graphical data are sketched and elucidated. Likewise substantiation of HAM solutions with preliminary investigation are given.
