In this article, mathematical model is developed
for transport phenomena in an incompressible viscous fluid
regime adjacent to a rotating vertical cone with thermal radiation
and transpiration effects. The governing equations for
the pertinent geometry are non-dimensionalized by employing
specified transformations. A set of resultant equations
are solved by numerical method. The solutions of this model
are carried out under physical realistic boundary conditions
to compute velocities, temperature and concentration functions
distributions. The results are compared with previously
available existing results. The excellent agreement has been
found. The effect of thermal radiation, transpiration (surface
injection/suction) and Forchheimer parameters, thermophoretic
coefficient and relative temperature difference
parameter on flow characteristics is illustrated graphically.
It is observed that substantial influence has been exerted on
flow characteristics, heat transfer rate (Nusselt number) and
mass transfer rate (Sherwood number) for various values of
transpiration parameter. The wall thermophoretic velocity
changes according to the variation of physical parameters
