Query: Integral analysis of laminar indirect free convection boundary layers
  with weak blowing for Schmidt no. ~ 1   Laminar natural convection at unity Schmidt number over a horizontal surface
with a weak normal velocity at the wall is studied using an integral analysis.
To characterise the strength of the blowing, we define a non-dimensional
parameter called the blowing parameter. After benchmarking with the no blowing
case, the effect of the blowing parameter on boundary layer thickness, velocity
and concentration profiles is obtained. Weak blowing is seen to increase the
wall shear stress. For blowing parameters greater than unity, the diffusional
flux at the wall becomes negligible and the flux is almost entirely due to the
blowing.
