Influence of Height Difference between Inlet and Outlet Center on Thermal Stratification in Rooms

Abstract:

For thermal natural ventilation, buoyancy plumes deriving from heating source make thermal stratification in room. The height difference between inlet and outlet is one of the important factors influencing thermal stratification. Taking a representative civil building with inside heating sources as the research object, using the technique of CFD, changing the height difference between inlet and outlet center, this paper gives simulation on the fluid field caused from thermal natural ventilation, analyzes the velocity field and temperature field under different simulation conditions, presents the influence rule of the height difference between inlet and outlet on thermal stratification in rooms. The results can provide a theory reference for natural ventilation system design in domestic buildings.
