Aspect ratio effect on the prediction of boundary layer interference in steady natural convection inside heterogeneous enclosures

Numerical Study of 2-D Natural Convection in a Square Porous Cavity: Effect of Three Mode Heating

“…Lage et al [13], have studied the phenomenon of flow interference caused by discrete, solid objects placed inside fluid saturated enclosures under natural convection. Their analysis confirms and quantifies the predominance of the horizontal interference when the enclosure becomes shallow ( 1 A > ).…”

Numerical investigation of viscoplastic fluids on natural convection in open cavities with solid obstacles

“…As the Ra number decreases, the thermal boundary layer increases, and the fluid flow deviates from the columns located at the ends to the other central columns. This behavior is known as the interference effect of the blocks [ 16 , 18 , 24 , 25 , 38 ]. The buoyancy forces that push the fluid close to the surface tend to migrate to the least resistive path to flow between adjacent columns of blocks, which can also be corroborated by the appearance of plastic regions in the end channels (see Fig.…”

“…In recent years, studies on natural convection in cavities containing solid blocks have been intensified, and there is an apparent scientific concern about the effects that bodies exert on the fluid flow field and heat transfer. Several investigations in closed cavities can be found [ [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] ]. However, there are few studies on open cavities.…”
