| Abstract: | The solution of a non-linear boundary value
problem arising due to the steady flow of an incompressible second-order fluid
(flowing with a small mass rate of symmetrical radial outflow m, taken negative for a net radial
inflow) under finite rotating disc (enclosed within a co-axial cylindrical
casing) has been obtained numerically using finite difference method. The
resulting equations are converted into a set of difference equations. Starting
from the known values of flow functions for small values of the Reynolds
number, the solution is extended for larger Reynolds number by making use of
Newton-Raphson iterative method and Gauss elimination method. Effects of second
order forces in the flow on the velocity field have been investigated in detail
in the regions of recirculation and no-recirculation for the cases of radial
outflow and inflow and illustrated graphically. Such flows are useful in
mechanical and chemical industries. |
