Abstract
The steady boundary layer flow of nanofluid over an exponential stretching surface is
investigated analytically. The transport equations include the effects of Brownian
motion parameter and thermophoresis parameter. The highly nonlinear coupled partial
differential equations are simplified with the help of suitable similarity
transformations. The reduced equations are then solved analytically with the help of
homotopy analysis method (HAM). The convergence of HAM solutions are obtained by
plotting
h
-curve. The expressions for velocity, temperature and nanoparticle
volume fraction are computed for some values of the parameters namely, suction
injection parameter
α
, Lewis number
Le
, the Brownian motion
parameter
Nb
and thermophoresis parameter
Nt
