چكيده لاتين :
Mixed convection is a fundamentally significant heat
transfer mechanism that occurs in selection industrial
and technological applications.
In this study, we first modeled the laminar mixed
convection inside rectangular enclosure with moving
wall and Aspect Ratio=10 and then the results were
compared with other investigators. After showing
verity of results, we continue our investigation with
turbulent flow using RNG k -e and standard k -e .
The results show that the turbulence intensity depends
on the position. For example, in vertical walls and
boundary layer, the flow is laminar and flow in center
of enclosure is turbulent.
