Abstract: | An analysis is presented for the steady non-linear viscous flow of an incompressible viscous fluid over a horizontal surface
of variable temperature with a power-law velocity under the influences of suction/blowing, viscous dissipation and thermal
radiation. Numerical results are illustrated by means of tables and graphs. The governing partial differential equations are
converted into nonlinear ordinary differential equations by a similarity transformation. The effects of the stretching parameter
n, suction/blowing parameter b, Prandtl number σ, Eckert number Ec(Ec * )E_{c}(E_{c}^{ *} ) and radiation parameter N
R
are discussed. Two cases are studied, namely, (i) Prescribed surface temperature (PST case) and, (ii) Prescribed heat flux
at the sheet (PHF case). |
