Sakiadis flow
Figure 12 Effect of Soret number on the temperature profiles
Effects of various parameter on concentration
profiles
This section considers the influence of the flow parameters on the
concentration profiles and depicted in Figures (13) to (18). Figure (13)
shows \(D_{f}\) effects on Blasius and Sakiadis flows. It is observed
that concentration profiles increase as \(D_{f}\) increases for Blasius
flow but experiences a swirling first effect and then decreases for the
Sakiadis flow. Figure (14) shows that increase in Ecdecreases for Blasius flow but for Sakiadis flow, the concentration
profiles experiences a decrease at the boundary layer and later
increases at the free stream. Figure (15) shows that the concentration
profiles decrease with increase in \(Gr_{x}\) for Blasius flow and the
Sakiadis flow. It can be seen from Figure (16a) that increase in\(M_{x}\) have dual effect on the concentration profiles of Blasius
flow. It is observed that concentration profiles increase in the
boundary layer but decreases towards the free stream along the boundary
layer. While the concentration profiles remains unchanged initially away
from the plate, it later increased towards the free stream as \(M_{x}\)increased for Sakiadis flow (see Figure (16b)). Figure (17) shows the
influence of \(\Pr\) on the concentration profiles for Blasius and
Sakiadis flows. It is observed that Blasius flow experiences decrease in
the concentration profiles with increase in \(\Pr\) whereas Sakiadis
flow experiences increase in the concentration profiles with increasing
values of \(\Pr\). Figure (18) shows the influence of Sr on
the concentration profiles and it is observed that the concentration
profiles decreases with increase in Sr for the Blasius flow
with dual effect for the Sakiadis flow. These analysed results are in
agreement with existing literatures.
