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 (۱۰۳ - ۱۰۶), aspect ratio (۱.۰ – ۲.۰), wave ratio (۰.۰ - ۰.۴۰) concerning a fluid with Pr = ۰.۷۱. 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.
