چکیده مقاله :
Mixed convection is a fundamentally significant heat transfer mechanism that occurs in selection industrial and technological applications. In this study, first the laminar mixed convection inside rectangular enclosure with moving wall and Aspect Ratio=10 is modeled and then the results are compared with other investigate. After showing varity of results, the investigation is continued with turbulent flow using RNG and standard . The results indicate that the turbulence intensity depends on the position. For example, in vertical walls and boundary layer, the flow is laminar and it is in the center of enclosure turbulent.
