Abstract :
In this paper, we propose radial basis functions (RBF) to solve the two dimensional
ow of
uid near a
stagnation point named Hiemenz
ow. The Navier-Stokes equations governing the
ow can be reduced to an
ordinary dierential equation of third order using similarity transformation. Because of its wide applications
the
ow near a stagnation point has attracted many investigations during the past several decades. We satisfy
boundary conditions such as innity condition, by using Gaussian radial basis function through the both
dierential and integral operations. By choosing center points of RBF with shift on one point in uniform grid,
we increase the convergence rate and decrease the collocation points.
