Two-dimensional laminar forced
convection over an inclined flat plate with an unheated starting length was
investigated numerically for both constant surface temperature and constant
heat flux boundary conditions. The numerical study was implemented using the
commercial software ANSYS Fluent 15.0. Air is used as working fluid. The
influence of Reynolds number, inclination angle and the length of unheated
plate on velocity and temperature distributions, surface temperature, surface
heat flux and local Nusselt number was investigated. The results show that
Reynolds number, inclination angle and the length of unheated region of plate
play important role on heat transfer from the plate. It is seen that Nusselt
number increases with increasing Reynolds number and inclination angle of
inclined flat plate but decreases with increasing the length of unheated region
of plate.
