Abstract
Marangoni-forced convection boundary layer flow of a water-based ferrofluid containing ferroparticles including magnetite ( Fe 3 O 4 ), cobalt ferrite ( CoFe 2 O 4 ) and ferrite from a stretching sheet is studied here. The effects of an induced magnetic field for both non-isothermal wall and constant heat flux conditions are considered. Applying a similarity transformation, we have reduced the governing equations into a set of nonlinear ordinary differential equations. The reduced equations are solved by using Maple software. In the presence of strong Marangoni effects, the reduced equations are solved and the influence of Prandtl number (Pr), magnetohydrodynamic body force parameter (ᵦ ) , reciprocal of magnetic Prandtl number (α) and solid volume fraction (ɸ) on velocity, temperature and magnetic steam function distributions as well as on the missing slopes are investigated.
