| Summary: | This study aims to investigate the thermal boundary layer over a vertical plate in porous medium
with a convective surface boundary condition. The governing systems of partial differential
equations subject to the boundary conditions are transformed into the system of ordinary
differential equations by employing the similarity transformation. The bvp4c method in Matlab
software is used to numerically solve the equations. With the use of graphical and tabular data,
the velocity and temperature profiles for various parameter values is obtained, analyzed, and
discussed. The effects of the governing parameters involved including permeability parameter
K and the buoyancy parameter λ are examined and discussed. The local Nusselt number and
skin friction coefficient increase as the permeability parameter's K value rises. The results
suggest that dual solutions for opposing flow and the solution is unique for assisting flow. The
results also shown that by increasing K, the permeability parameter, will increase the range of
solutions. Lastly, the permeability parameter, K, has the consequence of expanding the range
values of buoyancy parameter, λ for which solutions are discovered. |
