3. Results and discussion
To study the effects of magnetic field and Reynolds number on
the velocity field we have presented the non-dimensional velocity
u1 against g in Figs. 2–5 for several values of magnetic
parameter M2, Reynolds number Re, slip parameters b1 and
b2 with P = 1. It is seen from Figs. 2 and 3 that the fluid velocity
u1 decreases with an increase in either magnetic parameter
M2 or Reynolds number Re. This can be attributed to the
presence of Lorentz force acting as a resistance to the flow
as expected. The larger values of the Reynolds number correspond
to higher suction/injection strength and hence clearly
decreases the fluid velocity as illustrated in Fig. 3. Figs. 4
and 5 shows that the fluid velocity u1 increases with an increase
in slip parameter b1 while it decreases with an increase in slip
parameter b2. We have plotted the temperature distribution h
against g in Figs. 6–8 for several values of Brinkmann number
Br, Reynolds number Re and Peclet number Pe. It is seen from
Figs. 4–8 that the fluid temperature h increases with an
