AB  - The present study is concerned with the physical behavior of the combined 
effect of nano particle material motion and heat generation/absorption due to the effect of 
different parameters involved in prescribed flow model. The formulation of the flow 
model is based on basic universal equations of conservation of momentum, energy and 
mass. The prescribed flow model is converted to non-dimensional form by using suitable 
scaling. The obtained transformed equations are solved numerically by using finite 
difference scheme. For the analysis of above said behavior the computed numerical data 
for fluid velocity, temperature profile, and mass concentration for several constraints that 
is mixed convection parameter λ<sub>t</sub>, modified mixed convection parameter λ<sub>c</sub>, Prandtl 
number Pr, heat generation/absorption parameter δ, Schmidt number Sc, thermophoresis 
parameter N<sub>t</sub>, and thermophoretic coefficient k are sketched in graphical form. Numerical 
results for skin friction, heat transfer rate and the mass transfer rate are tabulated for 
various emerging physical parameters. It is reported that in enhancement in heat,
generation boosts up the fluid temperature at some positions of the surface of the sphere.
As heat absorption parameter is decreased temperature field increases at position X = π/4
on the other hand, no alteration at other considered circumferential positions is noticed.
