CFD and zonal approaches: comparison and validation

This paper deals with comparison between the CFD method and the zonal one, and also model experimental validation. The zonal method consists of a dwelling decomposition in several isothermal air zones, in contact with walls. 

This work comprises two parts :

• -comparison between zonal and CFD approaches : the studied case is a heated and ventilated room. Two zonal  models  are  achieved :  isothermal  and  non isothermal, using ALLAN. Simulation software. The CFD model is a low Reynolds number k- type using CFX code,
• comparison   between   non   isothermal   model calculations and experimental data : tests took place in a 2-rooms apartment.
