The present examination is considered to
research the steady, boundary layer flow of Casson fluid over a
stretching sheet by taking into consideration of suction and
injection effects. External magnetic field which is uniform is act
on the present model. In fact the nonlinear differential equations
are derived from the present flow by utilizing the appropriate
transformations. Thereafter exact and numerical solutions are
obtained. Impacts of flow influenced parameters of present study
for instance Casson fluid parameter, magnetic parameter,
suction and injection are analyzed by means of graphs and
tables. After that, numerical outcomes which are get hold of by
the convergent technique i.e. fourth order Runge-Kutta method
with shooting technique and exact solutions are validated by
comparing the existing literature. From this comparison there
exist a good correlation between present analysis and literature.
The outcomes demonstrate that mainly, velocity of the fluid is
diminished for increasing estimations of Casson fluid parameter
and impact of parameter of magnetic field.
