Abstract :
This paper expresses a numerical study of flow features and heat transport inside enclosure. Governing equations will
be discretized by finite-element process with a collected variable arrangement. The assumptions of the Grashof number (103 - 106),
aspect ratio (1.0 – 2.0), wave ratio (0.0 - 0.40) concerning a fluid with Pr = 0.71. Streamlines and isotherm lines are utilized to show
the corresponding flow and thermal field inside a cavity. Global and local distributions Nusselt numbers are displayed for the
before configuration. Finally, velocity and temperature profiles are displayed for some selected positions inside an enclosure for a
better perception of the flow and thermal field.
