9] studied the above mention heat transfer over a stretching surface with variable heat flux in micropolar fluids in the absence of the magnetic field (H = 0), the temperature buoyancy parameter (G = 0), and the local heat generation parameter (Q = 0).
The solution of Eqs (9)-(12) is subjected to the boundary conditions (13) in the absence of all the magnetic field (H = 0), the temperature buoyancy parameter (G = 0) and the local heat generation parameter (Q = 0) can be found in Pop et al.
We observe that both velocity and microrotation profiles increase with the increase of the material parameter(K), the velocity exponent parameter (m) and the temperature buoyancy parameter (G), while the temperature decreases with the increase of (K), (m) and (G) as shown in Figs.
Results of velocity and temperature profiles investigated for laminar developing mixed convection in vertical channel with different buoyancy parameter Gr/Re are shown in figures 3 and 6.
Figures 7 to 9 show the development of temperature profile for fixed buoyancy parameter Gr/Re.
This figure shows how the two hydrodynamic parameters are developing downstream of the channel at different heating rates represented buoyancy parameter Gr/Re.
