Lie group analysis for nanofluid flow past a convectively heated stretching surface

- Effects of chemical reaction on Nanofluid flow over a convectively heated stretching sheet have been studied.
- Magnetic field decreases the thickness of momentum boundary layer.
- The surface convection parameter is able to enhance heat transfer rate at the wall.
- Brownian motion and thermophoresis play an important role on fluid flow in the boundary layer region.
- The concentration boundary layer becomes thin for larger chemical reaction parameter.

The steady MHD boundary layer flow of an electrically conducting nanofluid past a vertical convectively heated permeable stretching surface with variable stream conditions in presence of chemical reaction has been investigated numerically. The transport model includes the effect of Brownian motion with thermophoresis in the presence of chemical reaction. The symmetry groups admitted by the corresponding boundary value problem are obtained by using a special form of Lie group transformations viz. scaling group of transformations. The influences of various relevant parameters on the flow field, temperature and nanoparticle volume fraction as well as wall heat flux and wall mass flux are elucidated through graphs and tables.
